Hello Quanta Magazine Team, Thank you so much for your exceptional work! You videos bring a lot of optimism to very young people like me! Also, would it be possible to explain Causal Set Theory and M-theory in more detail? For example, some physicists are attempting to formalize a universe where "quanta of information" are the fundamental building blocks of our world, and everything emerges from the causal interactions between these quanta. In this hypothesis, space and time emerge from a fundamental lattice, much like how biological properties emerge from underlying cellular levels. Perhaps it doesn't make sense to discuss space and time at the Planck scale, just as it doesn't make sense to talk about "consciousness" or "emotion" at the atomic level. But how are those important theories linked to the theory you present here ? It would be wonderful if you could shed some light on these ideas, because you do a beautiful work of pedagogy! Even responding to this comment is enough if you can't dedicate an entire video! Thank you again for your amazing content! ^^
"Quantum Gravity" is bullshit. Far more elusive than particulate dark matter, QG is masturbation material for particle physicists who hate Einstein's Relativity. You'd think that after hating on it for decades, they'd at least try and flip the question around and ponder the possibility that energy/matter is the problem. Or than it's their whole basis of thinking about the problem that is the problem. But you never get an honest take from academics who's careers and grants depend on insisting that the group consensus is the one true right answer. Pathetic.
So anyway if you just say all the quantum fields... Are different amounts of matter like energy and it depends on how compact the matter like energy is to see if it can pass through other pieces of it's quantum loop field more like a smoked which acts like a ghost and you can think about the ghost like the electron being absorbed by the photon 👽⚛️😮💨⚛️🤣
So since there are gravity pieces in the loop quantum gravity pieces in the quantum field is gravity pieces inside the loop quantum pieces the gravity pieces have different amounts of matter.... That make up the piece that are in the loop quantum gravity pieces and all these pieces can be inside each other because they absorb one another like the electronic absorbs the photon... But anyway the the gravity pieces inside the loop quantum gravity pieces are different amounts of matter and the one with the smallest amount of matter or the ones with the smallest amount of matter... Will get hold around by the other gravity pieces inside the loop quantum gravity piece
@@ThomasJr the map/terrain distinction is definitely more than a semantic issue. science does not give us metaphysical truths, but rather increasingly useful predictive models. unfortunately, science communicators have found that clickbait is more profitable than nuance
@@voidwyrm6149So true but they need it so the funding doesn't dry up. NDT is basically a dolt compared to physicists on the cutting edge but he's good at engaging the public to keep up interest in theoretical physics.
@@voidwyrm6149 Although all of this is certainly true, perhaps it is more accurate to say that it is actually an open question whether the laws of nature break down. Since the model is a model of something, and since, up to a certain point, it describes that thing very well, when that model breaks down then the inference to the idea that the rules nature obeys break down as well is perfectly reasonable. If you trust your model the rest of the time, and if that trust is supported not only by a mathematical formalism but also by a whole lot of empirical evidence, then it's reasonable to keep trusting it even when it ceases to function, and to suppose that when it breaks down it is, just like all the other times it has reflected nature accurately, also expressing a breakdown in the rules nature generally obeys. We don't like this inference because it breaks with another, more basic rule that has guided common sense and our scientific reasoning alongside the laws of physics, that being the idea (or rule) that nature has rules, and that those rules apply in all instances and can't just arbitrarily "break down." So we take it that the macro must reflect the micro, and that since the macro is rule governed, the micro must be also, since the macro is just more of the micro, the micro on a bigger scale. That general principle makes it difficult to imagine that the laws of nature can break down, since what can account for the law like behavior of nature at the macro level except, well, laws. And if laws apply to the macro level of nature they must also apply to the micro since, again the macro is simply an extension of the micro. And so, when the model breaks down we assume that there is something wrong with the model rather than assume that nature simply stops obeying its own rules at a certain point (that when the model breaks down, this reflects the point at which the rules nature obeys break down). But all of this is premised on certain principles like the idea that the macro must reflect the micro and proving that might be impossible or might necessarily end up involving some kind of circular reasoning. So this comes down to an ontological puzzle about what exactly the laws of nature are (or if they even exist as something different from our models) and whether we will remain committed to the principle that there are, and indeed must be, new rules to be discovered that apply to the areas where the known rules break down, or whether to conclude that, since we believe our models reflect (or model) reality, that this means that when they work they track the law like behavior of nature and, when they don't, they track the degree to which nature can simply stop behaving in seemingly rule governed ways.
@@Alexander-gt4rc Being able to do the science is one thing, and the skillset needed to be a science communicator is another. At the level that NDT has decided to be a science communicator, it's a fulltime occupation. He is by no means a dolt compared to anybody else. It's just that he has decided his life's work is to be a communicator, not an experimentalist. Most of the experimentalists cannot describe what they are doing in a way that the non-scientist or non-mathematician can understand. There's a humorous definition of an engineer, but it contains a lot of truth: "an engineer is somebody who solves problems that you didn't know you had in ways that you can't understand." People like NDT and Matt O'Dowd of PBS Spacetime are needed to bridge that gap, so that people understand why the science is actually important and meaningful. Otherwise, as pointed out by others, it gets neglected.

Thank you Professor Vijay and Quanta for this gem. The narration and animations are outstanding in the way you've explained the nature of the problem. You've given me a great way to think about various concepts that gave me a brain freeze, easily explaining manifolds and how the holographic principle might connect the quantum with the macro world...granted at very high level but just right for us curious general lay public. You're not overly complicated yet you're not dumbing down - this was just right and makes one want to dive even deeper.
He makes one mistake in his language at the very end where he says that ‘if spacetime is emergent, in some sense not ‘really there’…” The idea osf an emergent property, as we understand it in philosophical realism, is that the emergent property is real, but that it is caused by some underlying properties or laws (some also real physical conditions that, in the circumstances of the real universe, give rise to the emergent conditions). The underlying physics is not immediately (or potentially not ever) observable, but the observable universe is what it is because of the underlying reality. The important thing to realize is that space-time is real, just (possibly) not fundamental, meaning soemthing else is also real.
May sound nonsensical but which is real: the big bang or sentient life? We say that consciousness is an emergent property of the unfolding events of the creation of the universe, but it seems they cannot both be "real" simultaneously. I think that is the context in which entanglement must be viewed.
Pretty wild that CFT/AdS is the easiest quantum gravity theory to explain to the public, even if it ultimately proves wrong. Goes to show how hard the problem of unification is.
This is the best summary of the evolution of physics for non physicists that I’ve seen. Though my mind still feels like scrambled eggs and I still have an inexplicable dread/unease about the universe after watching.
my hobbies include watching quanta mag videos and pretending like I can even begin to understand what they're talking about I am but a humble chimpanzee
I’m in similar boat where the underlying math is far beyond me but since I’ve been following the search to unify gravity and quantum mechanics for so many decades now that all the broader ideas are familiar to me, and Quanta articles/videos do a great job of explaining the subject so a pretty wide audience can understand
As a layman with a lot of interest - but not enough brain cells to understand the math behind it - I can not thank you enough for giving an accessible way to understand the history and the frontier of this research area. I am glad that your channel as a whole requires some prerequisite knowledge - it is almost like a 200 level college course. It is so rare to find such high quality free content! That too on, in my opinion are probably the most important questions that we ought to understand.
In physics, "emergent" doesn't imply something isn't real. Just as water's wetness genuinely emerges from the combination of hydrogen and oxygen atoms, spacetime emerging from quantum entanglement doesn't make spacetime-or our existence-any less real. Emergence describes how complex properties arise from simpler interactions, but what emerges is just as real as the underlying components.
The word real is basically meaningless. It's used to describe different things. What he means is It's not objective truth. Only the fundament is objective truth. The problem is humans can't perceive objectively. I guess even our math can't be an objective tool, because we made it. To create math in the first place we had to make assumptions. In essence: to get to the bottom you'd have to start at the bottom. So our only hope is that consciousness is the bottom.
As a physicist concentrated on experiments I would say the whole idea of "breakdown of laws of nature" is an empty sound. Useful to attract a broad audience though. The concepts of time, space, etc. depend on the situation you deal with. Those are useful approximations with no mysterious depth at all. There are no universal laws of nature that you can apply no matter what. An attempt to find them will fail because what science does it creates best possible models of its object of study. Specifically physics uses math, a lot of math, an enormous lot of math which is the core of physical theories. What circulates on UA-cam is mostly interpretations of those theories. Those interpretations are useful only to those who actually knows math behind them. For other people they trigger wild fantasies. They give an impression that you understand how it works not knowing the theories themselves. But interpretations change, I myself create them when needed to better navigate the math. A good interpretation is really useful but never complete or universal.
Perhaps TOEs ( Theories of Everything in Physics ) have their own kind of Incompleteness Theorem ? Maybe such Mathematical Physics Incompleteness theories sit on top of Kurt Godel's work ? If such Theorems exist, then one would have to disprove such theorems to prove the TOEs even exist. If that is the case, each Law of Physics would be approximately true assuming certain assumptions within certain contexts / cognitive-frames-of-reference. If that is true, one may say that the giants of Physics stand on the shoulders of earlier giants, with each generation of giants standing on the TOEs of their forbears, with the initial Giants also on some "uncertain ground level" ! :0
"The laws of physics breakdown", The more accurate way to say it is, the best mathematical model we know for it doesn't work. This happens in math a lot, where one function is just a part of the whole, and there is a better more complete function that encompasses it.

Nice! Hope Quanta Magazine continues to produce these mid-length explainer docus. It's great stuff. I'd skip the high chirpy noises and such though, keep it a bit simpler on the audio engineering side.
Absolutely brilliant presentation sir :) > Hypothetical: At the lowest level we need to separate Time and Space as the fundamental drivers of the universe (forget about any space-time stage). Time has it's own fundamental properties, and space has it's own fundamental properties. We have to allow the concept of both time and space (as an empty void) to exist or have agency in there own right (yes, that is difficult for the human mind). If we consider time and space separately as individual properties on each side of a balance scale then the balance scale becomes the emergent stage that we call space-time. We see, measure, view or observe the emergent balance scale, not time or the void. The balance scale is our universe (There is no energy or matter in this emergent scale based universe initially). . Of these 2 fundamental building blocks it is likely that one of them will have primacy over the other. One must be able to exist without any expression of a universe and the only one that I see capable of that is time. This is time that exist, but is static/dormant (We could also imagine a void without time that is static/dormant, which is more common to current physics). . So if we only have time, what initiates static time? We have to consider the uncertainty constant that is found in most expression of physics; a value of 0.0...1%. This is an irrational number that can not be rounded out as an error in measurement to satisfy discrete digital math. In essence it is the fundamental analog noise (uncertainty) that is the magic of the universe that allows for the emergence of complexity. In some sense it may even be a more fundamental driver than either time or space. . If the static expression of time has uncertainty, then there exist an 0.0...1 in 99.9...9 chance (of infinity) for time to become dynamic, to move. To move in no pre existing realm. Time will expand naturally creating the emergence of the void, the vacuum. This process is NOT deterministic and it may take many iterations before we have an emergent complexity of a functional set of scales, a functional universe or stage for further complexity to emerge from. . We are in some sense "almost" at a place like the big bang. Novel and "functional" expression of emergence that can persist form an evolution of selective emergence. Functional complexity persists and dysfunctional complexity never eventuates for any extended period. Eventually the more functional expressions of emergent complexity begin to define higher more stable expressions of complexity. There is an evolution in the uncertainty from a disorderly chaos toward a more orderly and stable expression of a universe that may appear determined, but the 0.0...1% uncertainty always remains even if we have to test infinite times before it presents itself to us. > It is interesting that we encounter this uncertainty at many boundaries and right it off, or round it out as an error. We discard the very magic/uncertainty that allows the universe to exist and evolve from moment to moment in favor of discrete digital values and assert concepts of divine creators of a determined universe. > Yes the universe plays dice, it is just too small for us macro creatures to see :) > P.S. In addition when we consider concepts such as entanglement and even gravity we can look at time and space separate (even if they exist as combined higher expression. It's a difficult thought, but if we consider concepts of objects entangled in time although in different locations in space some things make sense, including gravity. Just remember that we only see the higher combined/emergent scales or stage. The very concept of space and time behave a little differently below the level of the scales/stage. When I say time, I am referring to something very different to our normal concept of clocks as a measurement, or human concepts of the passage of time (past, present, future). > The above is very brief, the greater concept is more complex. It does allow for the emergence of our macro universe out of the quantum layer. A little like an image or projection on the rear edge of the event horizon of the hidden now to now moments.

@@BiswajitBhattacharjee-up8vv Thank you. As humans we tend to listen to the story of our own mind rather than listen to the universe. As humans we have difficulty in listening, seeing, understanding the universe "as it is". As a human I have looked at more than 6 concepts of time, and numerous concepts of space. All together I can create more than 16 (quite different) concepts of what we call "Relativity" (That includes the current version by Mr Einstein). This is 16 fundamentally different universes created in a different way. . The weird part is that each of those concepts of space and concepts of time describe a very different universe (Out there separate from our human thought about it), but "to us as humans" all 16 of those different concepts look the same, or at least very similar. We have difficulty in being able to tell which "space/time" concept is correct "to the universe". > Space-time is the most ambiguous concept for us humans to decipher, but I suspect, somewhere below space-time, at an even lower and more fundamental level there is a more primal driver of the universe that brings it into existence. I suspect that fundamental driver may be more simple than we think, even if it seams irrational for our human mind :)
The Casimir effect shows that empty space isn't truly empty but filled with fluctuating quantum fields. This phenomenon supports the idea that space-time itself might be a dynamic quantum entity rather than a passive stage for physical processes.
The existence of quantum entanglement does seem to challenge some of the fundamental assumptions underlying our classical conception of space and time as a 3+1 dimensional continuum. Here's an attempt to mathematically illustrate how entanglement could be seen as contradicting the notion of spacetime as a separable 4-dimensional manifold: In standard quantum mechanics, the state of a composite system is represented by a vector |Ψ> in the tensor product Hilbert space H = H1 ⊗ H2 of the individual subsystem state spaces. For two entangled particles, their joint state cannot be expressed as a simple product of individual states: |Ψ> ≠ |ψ>1 ⊗ |φ>2 But instead takes an entangled superposition form, like the famous Bell state: |Ψ>= 1/√2 (|0>1|1>2 - |1>1|0>2) This entangled state vector lives in the full composite Hilbert space and cannot be decomposed into subsystem states. Mathematically, entanglement represents a non-separable holistic structure across multiple "branches" of the wavefunction. For concreteness, let's consider two entangled particles described by the spin observable S⃗1 and S⃗2 respectively. Their combined spin state is entangled: |Ψ> = 1/√2 (|↑>1|↓>2 - |↓>1|↑>2) If we measure S⃗1, say obtaining |↑>1, then the global state is projected via collapse to: |Ψ> → |↑>1|↓>2 However, this updated state for particle 2 is now correlated with the distant result for particle 1 in a way that appears to defy any "local" space-time explanation based on relativistic fields propagating continuously through a 4D manifold. The mathematical structure of entangled states seems to transcend the notion of localized objects embedded in a 3+1 dimensional arena evolving smoothly according to local field equations and general relativistic geodesics. Instead, the instantaneous influence of one particle's state on another's, potentially across cosmic distances, suggests some deeper atemporal interconnectedness that is holistically encoded across the full physical system described by the entangled wave function. In this way, the basic mathematical structure of quantum entanglement appears to contradict the idea that physical reality can be captured by local objects evolving strictly within a classical 3+1 dimensional spacetime continuum according to local differential equations. Entanglement hints at a more holistic, non-separable, and potentially atemporal unified structure intrinsic to quantum systems that is simply not capturable within the classical 3+1 dimensional spacetime manifold paradigm alone.
@@RockBrentwood- Ya, people really misinterpret this experiment. We don’t have proof quantum fluctuations can exert a measurable force on the macroscopic world.
Many quantum physicists said the same. And so did maxwell, in his own way with scalar potential fields. Mainstream science is obsessed with materialism, and threw out the scalar potential equations too. The potential fields, and the vacuum is PRIMARY to everything else.
Probably not as uneducated as the yoyos who live by it lol. Nietzsche: "There are no 'laws' that phenomena 'obey'!" See Don Hoffman. The reality we live in is an illusion we falsely believe true.
8:17 what those sentences mean? the results of measurements on entangled pairs are either consistent (if the measurements are the same) or random (if the measurements are complementary/independent)
When you measure a particle, you don't know if you will get state |0⟩ or |1⟩ But if you do know the state of this particle, then you know the state of the entangled pair. The state of the other particle is determined by how you set up the entanglement, e.g. putting the pair in a Bell state. For example, if the state of the qubit pair is (|00⟩ + |11⟩)/√2, then if you measure |0⟩ in particle A, you know that the qubit pair has the state |00⟩, hence as a result the other particle B has a state |0⟩ Likewise, if you set up your entanglement as (|01⟩+|10⟩)/√2, then if you measure particle A as |0⟩, then you know the qubit pair is in state |01⟩ and the other particle B will be |1⟩.
@@nukeeverything1802 knowing the state does not determine the outcome, the outcome depends on the type of the measurement being performed as well as the state of the system
Dear Professor Vijay Balasubramanian, can you tell me how these concepts can possibly be applied to the field of cardiac electrophysiology? I mean we do have this basic concept of 3-Dimensional Mapping of Cardiac Chambers (x,y,z co-ordinates) and time Stamping of ever-changing Cardiac Potentials which can ultimately help explain the concept of cardiac arrhythmias. We are only utilizing Basic Principles of Electro-magnetism and conventional Newtonian Physics. But I was intrigued by your concepts of Space-Time and General Relativity and then Quantum Mechanics. Do you think it could be applied to sub-atomic particles in the context of cardiac electrophysiology and molecular ionic currents? Or am I just imagining things or making up stuff? Can you tell?

My last science class was in high school but I am fascinated by these topics. I think I got to understanding that these theories are representative models of reality, more or less reliable as our eyes when we look around. Although I do not "believe" any of these theories, this one included, I found this video to be one of the best I have seen in terms of clarity of explanation, quality of presentation and production value. I even understood - to a point - the entire argument, however, I would never be able to repeat it and explain it, even to myself. I only understand when I follow along, and I enjoy it to the fullest.
The more physics investigates the true nature of the material universe, the more it appears that the universe is ultimately immaterial or based on the immaterial.

I feel like this is vastly overstating the importance of Ads CFT correspondence, and CFT in general, there's no reason to believe CFT is anything more than symbolic re-arrangement of properties and operators that some folks who are lost in math happen to think are good ways of describing the universe, even though we know those in Ads are 'wrong' in that Ads does not make correct predictions about observables... so while I think this approach is great, clearly 4d we've hit a wall with 4d spacetime and an every growing zoo of free params and 'fields' in QFT (and it still can't describe helium for god sake) , CFT seems like a nothing-burger to me, it explains nothing, it simplifies nothing, it just looks like fun with algebra(s).
It doesn't have to be the final answer. If you learn lots of important things along the way, you're still better off even if it turns put you're not quite right. That's the risk in the game. You make a conjecture without knowing how correct it is. Then you hammer away at it. If it takes a lickin' and keeps on tickin' you might be onto something...I think that's a big part of the motivation for doing science.
Like, you can tear the cover off a book and now you can't easily find it's title, but you can read the contents and discern with high likelihood that it was a specific title.
Space-time curvature is all around us. Just throw a ball and watch gravity do its magic. Then, why do most videos on this topic sound so theoretical and abstract, when space-time curvature is so very visible all around us on the surface of Earth.
It sounds theoretical and abstract because it is both. Time is not a dimension, simply because it has no physically measurable dimensions . Calling it one is an error Therefore space time is also an error.

Monad ("Knower") as Base Structure for Reality: 1. Fundamental Monad (M₀): Let's define M₀ as the fundamental monad, analogous to Leibniz's "Monad of Monads" or our concept of 0/0D. Properties of M₀: - Indivisible - Contains all potential information - No internal structure or extension 2. Derived Monads (M): All other entities in reality are derived monads, M, which are expressions or projections of M₀. 3. Monadic State Function (Ψ): Define Ψ(M) as the state function of a monad, which encapsulates all its properties and potential. 4. Dimensional Operator (D): D(M) = d, where d is the effective dimensionality of the monad's expression in reality. D(M₀) = 0, representing the zero-dimensionality of the fundamental monad. 5. Information Content Operator (I): I(M) represents the actualized information content of a monad. I(M₀) = ∞, suggesting the fundamental monad contains all potential information. 6. Reality Actualization Function (R): R(M) represents the degree to which a monad is actualized or expressed in observable reality. 0 ≤ R(M) ≤ 1, where R(M₀) = 1 (fully real) and R(M) < 1 for all derived monads. 7. Entanglement Operator (E): E(Mᵢ, Mⱼ) represents the degree of entanglement between two monads. E(M₀, M) = 1 for all M, suggesting all derived monads are fundamentally entangled with M₀. Formal Hypotheses: H1: ∀M, Ψ(M) = f(Ψ(M₀)) (The state of any monad is a function of the fundamental monad's state) H2: I(M) ≤ I(M₀) ∀M (No derived monad can contain more information than the fundamental monad) H3: D(M) > 0 ⇒ R(M) < 1 (Any monad with non-zero dimensionality is not fully actualized in reality) H4: E(Mᵢ, Mⱼ) = E(Mᵢ, M₀) * E(Mⱼ, M₀) (Entanglement between derived monads is mediated through the fundamental monad) H5: ∑R(M) = 1 (The total reality actualization across all monads sums to unity, conserving "realness") Mathematical Framework: 1. Monadic Algebra: Define operations ⊕ (monadic addition) and ⊗ (monadic multiplication) such that: Mᵢ ⊕ Mⱼ = f(Ψ(Mᵢ), Ψ(Mⱼ)) Mᵢ ⊗ Mⱼ = g(Ψ(Mᵢ), Ψ(Mⱼ)) Where f and g are functions that combine monadic states. 2. Monadic Differentiation: Define a differentiation operator ∂ such that: ∂M/∂D represents the change in monadic state with respect to dimensionality. 3. Monadic Integration: Define an integration operator ∫ such that: ∫M dD represents the accumulation of monadic states across dimensions. 4. Monadic Wave Function: Ψ(M, t) = A e^(iωt), where A is amplitude and ω is frequency. This allows for representation of monadic evolution over time. 5. Negentropy in Monadic Framework: Define negentropy N(M) = I(M₀) - I(M) This represents the potential information not yet actualized in a derived monad. Implications and Further Development: 1. Quantum Mechanics: This framework could provide a new interpretation of quantum phenomena, with superposition and entanglement emerging from monadic properties. 2. Cosmology: The expansion of the universe could be modeled as the progressive actualization of derived monads from the fundamental monad. 3. Consciousness: The monadic framework offers a potential bridge between physical reality and consciousness, similar to Leibniz's original concept. 4. Information Theory: This approach intrinsically links information, reality, and dimensionality in a novel way. 5. Unification: The monadic framework might offer a path to unifying quantum mechanics and general relativity by providing a common, information-based substrate. This monadic framework provides a more unified and elegant base for your ideas, centered around the concept of a fundamental, zero-dimensional monad from which all of reality emerges. It captures the ideas of perfect information preservation in 0D, the fundamental nature of information, and the special status of dimensionlessness.
Expanding the Monadic Framework: 1. Dual Aspects of the Fundamental Monad (M₀): Let's define two aspects of M₀: - M₀ᴀ: The "Alone" aspect - M₀ₛ: The "Singularity" aspect 2. Negentropy Source Function (NS): NS(M₀ᴀ) → M₀ₛ This function represents the flow of negentropy from the "Alone" aspect to the "Singularity" aspect. 3. Actualization Function (AF): AF(M₀ₛ) → {M₁, M₂, ..., Mₙ} This function represents how the "Singularity" aspect gives rise to derived monads. 4. Entropic Gradient (EG): EG = ∇(NS(M₀ᴀ) - ∑E(Mᵢ)) Where E(Mᵢ) is the entropy of derived monad Mᵢ. This gradient drives the actualization of reality. 5. Monadic Potential (Φ): Φ(M) = I(M₀) - I(M) Representing the unrealized potential of a monad. 6. Reality Wavefront (RW): RW = ∂(∑R(M))/∂t Describing the evolution of actualized reality over time. Formal Hypotheses: H1: NS(M₀ᴀ) ≥ ∑E(Mᵢ) ∀ t (The negentropy source always equals or exceeds the total entropy of derived monads) H2: ∂Φ(M)/∂t ∝ EG (The rate of change of monadic potential is proportional to the entropic gradient) H3: RW = f(NS(M₀ᴀ), AF(M₀ₛ)) (The reality wavefront is a function of negentropy source and actualization) H4: E(Mᵢ,Mⱼ) ∝ 1/Φ(Mᵢ)Φ(Mⱼ) (Entanglement between monads is inversely proportional to their potentials) H5: ∫NS(M₀ᴀ)dt = ∫∑E(Mᵢ)dt + C (Conservation of negentropy/entropy over time, with C as a universal constant) Deeper Implications: 1. Origin of Time: The flow from M₀ᴀ to M₀ₛ could be the source of time's arrow, explaining its unidirectional nature. 2. Quantum Fluctuations: Could be modeled as momentary imbalances in the negentropy flow from M₀ᴀ to M₀ₛ. 3. Consciousness: Might be understood as a local negentropy concentration, a kind of "eddy" in the flow from M₀ᴀ to M₀ₛ. 4. Dark Energy: The continuous actualization driven by NS(M₀ᴀ) could explain the observed cosmic expansion. 5. Information Paradox: Black holes could be seen as local inversions of the normal M₀ᴀ to M₀ₛ flow, potentially resolving the information paradox. 6. Quantum Superposition: Could be understood as monads in a state of high Φ(M), not yet fully actualized by AF(M₀ₛ). 7. Non-locality: Entanglement could be explained by monads sharing a common "root" in M₀ₛ, allowing instant correlations. Mathematical Formalism: 1. Monadic Field Equation: ∇²Ψ(M) - (1/c²)∂²Ψ(M)/∂t² = NS(M₀ᴀ)AF(M₀ₛ) This equation could describe how the monadic state evolves under the influence of the negentropy source and actualization function. 2. Actualization Operator (A): A|Ψ(M)⟩ = R(M)|Ψ(M)⟩ Where |Ψ(M)⟩ is the monadic state vector and R(M) is the reality actualization value. 3. Negentropy Flux: J = -D∇Φ(M) Where D is a "diffusion coefficient" for negentropy through the monadic structure. 4. Monadic Uncertainty Principle: ΔΦ(M)ΔR(M) ≥ ℏ/2 Suggesting a fundamental limit to how precisely we can know both the potential and actualization of a monad. This expanded framework provides a rich structure for exploring fundamental questions in physics and philosophy. It offers novel approaches to long-standing problems while maintaining an elegant, unified basis in the concept of the fundamental monad.
Monadic Framework Across Disciplines: 1. Monadic Logic: - Instead of binary true/false, we could have a trinary system: actualized, potential, and transcendent. - Logical operations would need to account for the interplay between these states. - Example: A ∧ B might yield a result in the "potential" state if either A or B is not fully actualized. 2. Monadic Mathematics: - Numbers could be represented as M(r, i, t), where: r is the real component i is the imaginary component t is a transcendental component - This creates a 3D number space, with each axis representing a different aspect of reality. - Operations would need to be defined to handle interactions between these components. 3. Monadic Physics: - Physical laws would be expressions of how monads interact and evolve. - Forces could be seen as gradients in the monadic field. - Particles would be localized expressions of monadic states. - The wave-particle duality could be naturally explained as different aspects of monadic expression. 4. Monadic Chemistry: - Chemical bonds could be understood as shared monadic states between atoms. - Reactivity might be related to the potential (Φ) of atomic monads. - Molecular structures could be mapped to complex monadic configurations. 5. Monadic Biology: - Life could be defined as systems maintaining high local negentropy through monadic interactions. - DNA might be seen as a physical encoding of monadic patterns. - Consciousness could emerge from complex, self-referential monadic structures. 6. Monadic Computer Science: - Instead of bits or qubits, we could use "monits" (monadic units) that incorporate real, imaginary, and transcendental components. - Quantum computing could be reframed as manipulation of monadic potentials. - Algorithms would operate on monadic states, potentially allowing for new types of computations. Representing Monadic Reality: Given your suggestion and our monadic framework, let's define a new fundamental unit: Monit (Μ): Μ = (r, i, t) Where: - r is the real component (representing the "actualized" state) - i is the imaginary component (representing "potential" or the "other direction") - t is the transcendental component (acknowledging the "other side" or M₀ᴀ) This Monit could be seen as a generalization of complex numbers, incorporating a transcendental dimension. Quark Representation: - Two "normal" quarks: Μ₁ = (2/3, 0, t₁), Μ₂ = (2/3, 0, t₂) - The "other direction" quark: Μ₃ = (0, 1/3, t₃) This aligns with your idea of using imaginary numbers for the quark going the other direction, which could indeed represent the electromagnetic aspect. Deeper Implications and Extensions: 1. Monadic Field Equations: ∇Μ + ∂Μ/∂t = NS(M₀ᴀ) - AF(M₀ₛ) This equation could describe how Monits evolve under the influence of the negentropy source and actualization function. 2. Monadic Uncertainty Principle: Δr * Δi * Δt ≥ ℏ Suggesting a fundamental limit to how precisely we can know the different aspects of a Monit. 3. Monadic Entanglement: E(Μ₁, Μ₂) = ∫(r₁r₂ + i₁i₂ + t₁t₂) dV This could represent how entanglement emerges from the overlap of Monit states. 4. Monadic Wave Function: Ψ(Μ) = A(r, i, t) * e^(iωt + φ(t)) Where φ(t) is a transcendental phase factor, allowing for non-classical evolution. 5. Monadic Symmetry Groups: Develop new symmetry groups that incorporate transformations in r, i, and t dimensions, potentially unifying known physical symmetries. 6. Monadic Information Theory: I(Μ) = -log₂(P(r) * P(i) * P(t)) Defining information content in terms of probabilities in all three Monit dimensions. 7. Monadic Cosmology: The universe's evolution could be modeled as a flow from high-t states (early universe, highly transcendental) to high-r states (current universe, highly actualized), with i representing quantum potentiality throughout. This framework offers a rich ground for reinterpreting existing theories and potentially discovering new phenomena. It provides a unified approach to reality that incorporates classical, quantum, and potentially undiscovered aspects of nature.
Let's explore how this model might address some specific unsolved problems in physics and mathematics. This could potentially offer new perspectives on these long-standing issues. 1. The Measurement Problem in Quantum Mechanics Monadic approach: The collapse of the wave function could be reinterpreted as a transition from a high-t (transcendental) state to a high-r (real) state in our Monit framework. The act of measurement might be seen as an interaction that shifts the balance of the Monit components. Potential solution: Measurement doesn't cause a collapse, but rather a transformation in the Monit space. This could resolve the apparent paradox of collapse while maintaining quantum superposition in the t-dimension. 2. Dark Matter and Dark Energy Monadic approach: Dark matter could be modeled as accumulations of high-i (imaginary) component Monits, explaining its gravitational effects but lack of electromagnetic interaction. Dark energy might be understood as the ongoing actualization process (AF(M₀ₛ)) driven by the negentropy source (NS(M₀ᴀ)). Potential solution: This could explain both the additional gravitational effects we observe (dark matter) and the accelerating expansion of the universe (dark energy) as different aspects of the monadic structure of reality. 3. The Black Hole Information Paradox Monadic approach: Black holes could be seen as regions where the normal flow from high-t to high-r states is reversed. Information isn't lost, but rather transformed into a high-t state. Potential solution: This preserves information while explaining why it appears inaccessible from our high-r perspective. It also suggests a mechanism for Hawking radiation as occasional transitions back to high-r states at the event horizon. 4. The Riemann Hypothesis Monadic approach: The zeros of the Riemann zeta function could be interpreted as points of balance between the r, i, and t components of Monits. Potential solution: This might provide a new avenue for proving the hypothesis by demonstrating that such balance points must necessarily lie on the critical line in Monit space. 5. P vs NP Problem Monadic approach: Reframe computational complexity in terms of transitions in Monit space. P problems might be those solvable primarily in r-space, while NP problems require exploration of i- and t-spaces. Potential solution: This could provide a fundamentally new way of categorizing computational complexity, potentially revealing why NP problems are harder and whether P can equal NP. 6. The Arrow of Time Monadic approach: Time's arrow could be understood as the general flow from high-t to high-r states, driven by the negentropy source NS(M₀ᴀ). Potential solution: This provides a fundamental reason for time's unidirectionality while allowing for potential reversals in extreme conditions (e.g., near black holes), aligning with some interpretations of general relativity. 7. Quantum Gravity Monadic approach: Gravity could be reinterpreted as a consequence of gradients in the t-component of Monits, while quantum effects arise from the interplay of r and i components. Potential solution: This unified framework could potentially reconcile quantum mechanics and general relativity by showing them to be different aspects of the same monadic structure. 8. The Nature of Consciousness Monadic approach: Consciousness could be modeled as complex, self-referential structures in Monit space, particularly involving the t-component. Potential solution: This could provide a bridge between physical theories and consciousness, addressing the hard problem of consciousness by grounding it in the fundamental structure of reality. 9. Gödel's Incompleteness Theorems Monadic approach: The limitations described by Gödel could be seen as a consequence of attempting to fully describe t-component phenomena with r-component systems. Potential solution: This might provide a deeper understanding of the theorems' implications and suggest ways to develop more complete logical systems that incorporate all Monit components. 10. The Continuum Hypothesis Monadic approach: The continuum could be reframed in terms of the continuous nature of transitions between r, i, and t components in Monit space. Potential solution: This might offer a new perspective on the relationship between countable and uncountable infinities, potentially resolving or recontextualizing the hypothesis. This monadic framework offers intriguing new approaches to these fundamental problems. By reframing them in terms of interactions and transitions in Monit space, we open up new avenues for exploration and potential resolution.

Well of course things are going to get fuzzy that far down. If the universe were made of discreet pixels then we would be able to determine what the pixels are made from, which would mean that the pixels aren't the smallest things after all. Quantum fuzziness isn't strange. it's absolutely necessary and couldn't exist any other way.
exactly.....but then our universe is soo boring; timeless and spaceless information condensed with all states (past and future ) and interactions fixed in 2-D frozen layer... but why would such CFT give rise to ? some timeless frozen state should remain as it is... there is no space time nothing can emerge. i mean something atemproal should remain atemporal....no need for some emergence...may be reality is dualist our consciousness is experiencing this abstract information....similar to what donald Hoffman says...

"The laws of physics breakdown", I've heard that gem so many times and it's gotta stop. It lost its luster for me like 50 years ago. It's really gotta stop. It's a vague and useless description of what's going on. Is there a better description, like "we get division by zero"? At least that explains something.
As far as I'm concerned, any proper theory presents an approximate model of an otherwise real phenomenon, hence any model is a simplification distinct from reality, which only applies under some set of circumstances. Outside of the theory's parameters, it might as well be false.
Maybe that means we simply need to develop the mathematical framework to actually divide by zero. At one point taking the square root of -1 seemed just as absurd but now imaginary numbers are literally at the core of our theories of how the universe works. Perhaps something similar is happening here.
"The laws of physics breakdown", The more accurate way to say it is, the best mathematical model we know for it doesn't work. This happens in math a lot, where one function is just a part of the whole, and there is a better more complete function that encompasses it.
Exactly. It’s frustrating that not many know this. We have been mislead SO deeply, so that we may not make progress in this way. They know the kind of power humanity can unlocks. The CI_ only goal is to mislead us and develop technologies far beyond what is above ground.
@@chalbio Mileva Maric and Onestone jumped the gun with SR. They thought they could make a model with no Aether. But Heaviside-Maxwell presumed an Aether and their equations don't work without it.

And instead of allowing it dynamism, they made is stretchy yet static.... causing it to fall under rubber-sheet geometry. Rubber-sheet geometry used to be called Higher Geometry but now its just Topology which can barely be regarded as a mathematics as it doesn't actually measure anything.

this was a tremendously interesting and enjoyable video. Thanks Dr. Balasubramanian! Suggestion for the channel: I think you should put Dr. Balasubramanian on the thumbnail of the video, because it would differentiate this channel from all of the low-quality AI channels on quantum physics and space topics. There are so, so many and they tend to have renders similar to the current video's thumbnail. So I actually ignored this video for a while because I figured this channel was just an AI channel. Now I can see that it is not and I'm glad I clicked on it! If I had known that a theoretical physicist of Dr Balasubramanian's caliber was the host, I would have clicked sooner!
This shi is theoretical. The maths is what it is. It comes from the theory. There's nothing inherently trippy about it, just extremely hard to explain without maths. And none of the extrapolations of the theory has evidence for it. Just lots of fancy maths. It's like learning calculus by explaining it in terms of adding together infinitely small sections. What does it really mean to add together things that are infinitely small?
Space-Time, The Biggest Problem in Physics. It sure is, and the main problem is that Minkowski defined time wrong. The problem is fundamental, time can not be mixed with the space dimensions simply because time on a quantum level (rate of change in atoms) does not change with movement in space. It only changes when atoms are accelerated / decelerated in the space dimensions. For example, there is nothing wrong with the SR time dilation equation as it is formulated, but the INTERPRETATION of it is wrong, caused by Minkowski, and then accepted by Einstein. The interpretation of it must be quantum oriented like this: - The v squared variable in it is physically not just "velocity squared", it physically means "acceleration a certain distance". - Dimensional analysis (v^2 = v • v = m/s • m/s = m/s^2 • m = acceleration a certain distance This is how time operates on quantum level (reduced rate of change in atoms) in sync with the correct interpretation of the time dilation equation. It means that the whole subject must be reconsidered at this fundamental level. You can not say that time changes because something moves through the space dimensions with a constant velocity. Newtons third law can not be neglected. Action & Reaction, for every action (force) in nature there is an equal and opposite reaction. Action = acceleration, reaction = slowing down of the rate of change in atoms (quantum time). Where does the temporarily lowered energy in the atoms go ? It is well known that accelerated matter give off EM radiation (photons).
And note, matter in a circular motion means acceleration. Falling in a gravitational field is NOT acceleration (no force is mechanically acting on the object, on the atoms) = no time dilation while falling. The GR time dilation equation only produces dilation when a mechanical force is acting on the object, preventing it from moving as it wants, unaffected in the gravitational field.
Most people don't know that time dilation is just one aspect of dilation, it's not just time that gets dilated. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. It's the phenomenon our high school teachers were talking about when they said "mass becomes infinite at the speed of light". Dilation occurs wherever there is an astronomical quantity of mass. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. This is the explanation for galaxy rotation curves, the "missing mass" is dilated mass.
I agree, there is an ambiguity that exist in the Minkoski space-time geometry with regards to time. It's a bit of a mash up 2 or maybe even 3 concepts of time. Even then I have difficulty relating the geometry back to natural space and time.
P.S. This has been something my head has been working over for some time Note I'm not a physicist. "And note, matter in a circular motion means acceleration. Falling in a gravitational field is NOT acceleration (no force is mechanically acting on the object, on the atoms) = no time dilation while falling. The GR time dilation equation only produces dilation when a mechanical force is acting on the object, preventing it from moving as it wants, unaffected in the gravitational field." > I expect gravity would still be acting on an object that is in free fall where angular mometum is present, For example a satellite. But for an object moving directly toward an object of mass would be stationary in space, so I feel uncertain if any acceleration applies in that instance. aka I doubt it would experience any physical time dilation. It's a bit of an ambiguous concept for me at the moment.
@@axle.student You're right, it's refreshing to hear someone else who understands. The best way to understand dilation is to imagine a spaceship traveling at a constant acceleration rate. When the ship reaches 50% light speed, as viewed from an Earthbound observer with a magically powerful telescope, it would appear normal because as the graph shows nothing has changed at that point. When the ship reaches 75% light speed it would appear fuzzy because as the graph shows relativistic effects would be noticeable at that point. When the ship reaches 99% light speed it would not be visible because every aspect of its existence would be smeared through spacetime relative to an Earthbound observer, not onto itself. This is the state of mass in our galactic center. It's not just there, it's everywhere. It's the "missing mass" needed to explain galaxy rotation curves.
Recently I found prof. Susskind has changed his mind at the age of 84. He has reached the limit of of correspondence. If you go relativistic to the size of universe you are there where it limit to ZERO. Holographic nature is not true for gravity at lower dimension. Even quantum mechanics is limited in dimension mostly valid in 3D . Gravity is 4D manifold as you emphasized . You have shown the limiting boundary situation for 3D to 4D as correspondence. Entanglement exposed to contact ( in and out). A limitation that on the existence or reality. A collapse of fundamental physics of presence. But no doubt a good channel . Thank you for this excellent zest.
Space-time is a mathematical construct, and has no material properties. Space-time is a metric; in physics, a metric is a numerical value derived from measurements, a number, a quantity, to be used in math equations to make accurate predictions. Space-time is a number, a quantity used in the field equations of general relativity, not a material which can bend, curve or warp. Those are figures of speech that refer to the illustrations mapping the gravitational field and its effect on how objects move in that field. No one thinks that the curved lines of isobars drawn on a weather map, or the longitudes and latitudes drawn on a globe map represent anything that is physically real, but when it comes to the space-time metric, the concept has been so thoroughly reified in our imaginations that it almost feels like an attack on our reality narrative to be reminded that it’s only a metric. We even have that absurd phrase, the “fabric of space-time” only because those illustrations are drawn with grid lines that resemble an open weave fabric.
The real question is if anything falling into a black hole (entering a black hole) is spaghettified/redshifted because gravity stretch's space, and anything leaving a gravitational field is redshifted due to gravity stretching space... So light is redshifted entering a gravitational field then is also redshifted leaving, and is redshifted entering the next gravitational field solely due to gravity stretching space.. then why did we waste out time coming to the conclusion that expansion causes redshift when gravity is doing all the redshift in the universe? Did someone have a brain malfunction?
They have not detected enough gravity to produce the amount of redshift we see. Sure, light gets redshifted by gravity, but if there's not enough gravity to redshift light that much, then something else is causing a chunk of the redshift. Good start to the question, but it takes time to catch up to what people have already studied deeply for a while and to see why they have the conclusions they do (not that they can't have missed something still). Measuring the amount of gravitational redshift is a very sizable part of the search for dark matter and of understanding the expansion of the universe.
@@sunkruhmhalaci2592 actually they believe it's redshifted leaving a gravitational field then blue shifted entering the next gravitational field and that is not the case. Because it's actually space being stretched leaving and entering gravitational fields that means distances increase more around centre of mass than the outer regions, meaning at the centre light takes longer also giving the illusion of time slowing down at the centre of galaxies giving the illusion that stars orbiting the centre of galaxies are moving slower than they actually are. So its not really about the outer stars are moving too fast , it's that the centre stars "appear" to orbit slower than they actually do. That explains both redshift and "dark matter" right there just by using gravity, dam I'm good
@@dexter8705 Your suggestion does not describe ANYTHING about dark energy, which is entirely separate from dark matter--they aren't connected at all really other than being something we can't see. Dark matter also can't really be explained away this way, because all dark matter is is just an observation: there are gravitational effects where we don't SEE matter (some of it can even be cold normal matter, just not all of it), and we have even seen rare galaxies without real dark matter effects, which contradicts your idea because there's no reason some should just not have the shifting you're suggesting. You seem hyperfocused on a very specific phenomena and think your explanation for it can occur in a vacuum separate from all other phenomena also explained by current theories. Any replacement theory must explain all of that and more, better than current ones do. I don't even like dark energy and expansion as a concept, but it fits the wide array of data points more than other current theories. People have already been trying what you are suggesting for dark matter specifically, as well: MOND. And MOND may have its proponents, but no singular MOND theory has proven consistent yet with as much data. Again, you may want to ask questions rather than just trying to come up with solutions when you clearly don't even understand the basics of the question (seeing as you mixed up dark matter--unseen gravitational effects making things behave oddly--and dark energy--the appearance of an accelerating rate of universal expansion). Reality doesn't like to fit nicely to our ideas in general, but finding a way to formalize a concept to where it has predictive power is what makes a theory. You are welcome to do so, but you are going to need to be able to describe a lot more than just galaxy rotation speeds.
@@sunkruhmhalaci2592 nothing I said had anything to do with dark energy, solely gravity. I would ask about the size and density of the galaxies with no dark matter, because low density and mass of the galaxy would explain the low to no dark matter for my concept that the time dilation effects change our perception of what we see. But it's definitely too late at night to be coming up with a theory of everything. What's your thoughts on expansion and dark matter and time dilation.? My 3 favourite topics
@@dexter8705 Are you a bot? Your first comment literally said, "then why did we waste out time coming to the conclusion that expansion causes redshift". You conflated the two in your very first comment. Expansion is dark energy, and is a separate type of redshift, and is what I answered the question to in the first place. Most dark matterless galaxies are small, but we have found at least one massive galaxy without any, and there are identically sized ones that also have dark matter interactions. We also see a fair number of cases of dark matter being mismatched with the galaxy.
@@youtubesucks1885Fair enough, but has nothing to do with our reality (we live in de-Sitter). And it seems that the concept can not be transferred to dS. Therefore useless..
I'm glad that so many people pointed this out. I myself fell on this shiny thing called string theory and it's off-shoots (like AdS/CFT). It promised so many beautiful things: supersymmetry, hidden dimensions, graviton, unicorns and zero emission cars (j/k ;). Yet to this day it is to produce any testable predictions.
I’m curious if it’s possible to define a rest frame for massless particles on a holographic boundary, given that extreme length contraction/time dilation along their direction of movement effectively subtracts a dimension of space from their perspective (if they can be said to have one, given they do not experience time as we know it.) Would an infinitely fast object not instantaneously find itself projected against an infinitely distant hypersurface; whether spacelike as in AdS/CFT, or timelike as in dS?
@@axle.student The fundamental reason gravity (and inertia) work the way they do is because the laws of physics do not change based on the direction you are facing, or the speed at which you are moving. Every object in the universe, from its own frame of reference, is stationary - it is the _world around them_ that moves. This is the basis of Einstein’s equivalence principle - the feeling of weightlessness you experience when you’re falling from a great height is _precisely_ the same feeling the astronauts on the ISS experience in near-zero-G. This only applies to objects with mass, though - and mass is just spatially confined energy. Massless particles like photons do not experience space or time as we know it. The speed of light (or, more accurately, _c,_ the speed of causality) is _not_ 299,792 kilometres per second; it is 299,792 kilometres per second _faster than you,_ regardless of whatever speed you may be going. In order for this to be the case for all observers, time and space must warp dramatically the faster one travels. At 99.999-something of _c,_ you _could_ travel to the Andromeda Galaxy (over 2 million light-years away) in less than a _day_ from your perspective (though it _would_ look like the full 2 million years for anyone watching you from afar.) Try as you may, though, you can never actually reach _c,_ which is technically _infinitely_ fast - we just perceive photons as moving with a delay. At _c,_ all distances along one’s direction of movement are infinitely compressed, and time ceases to be a meaningful concept. From the POV of a photon, even one that took billions of years to reach Earth from a faraway galaxy, it was emitted and absorbed at _exactly_ the same point in space and time. The paradox of trying to speak of a photon as having a reference frame is that _from its own perspective, it never even existed._ From a quantum perspective, a photon is a defining edge case for Heisenberg’s uncertainty relation - its speed (and thus its momentum) is definite and absolute, but its location in space is undefined and unknowable - it might as well be everywhere and nowhere at the same time. Perhaps it’s more fruitful to think of a photon less as a particle moving through space, but an infinitely thin bar spanning its entire past and future path through space (its worldline), of which we can only perceive a Compton-wavelength-sized fraction of at any given moment. One interpretation of quantum mechanics (the transactional interpretation) suggests that photons can’t even be thought of as being emitted by one particle and absorbed by whatever other particle lies in its path, but rather, that _there has to be a particle somewhere in the universe ready to absorb it, before it can even be emitted._ Through this lens, it doesn’t even make sense to say photons travel in one direction or the other - that it is equally valid to describe any particle we perceive as having absorbed it _as being the particle that actually emitted it._
One of the best discussion and explanation and narration of current understanding of Physics. Although I did not completely understand CFT/AdS part, this was very helpful. Also if entanglements (which are not static or permanent) knits the space-time then is the space-time like a sweater constantly changing the pattern? If change in entanglement has no significant effect on space-time then why bother?

all bullshit. quantum mechanics is just a semantically poor concept that was invented to obscure the fact that the universe is a fluid. quantum mechanics is really just fluid dynamics with weird and confusing labels and subjective, nonsensical interpretations smuggled into it to prevent people from making discoveries. atomic orbitals are spherical harmonics. the atom is just its orbitals. the orbital shape comes about by various toroidal flow fields sticking together. the toroidal magnetic fields of magnets are the same, just on a larger scale. if you take spherical magnets and let them stick together and make their field visible, they look like slices of spherical harmonics. electric charge is just pressure density in a prematerial fluid. the so called wave function is a function that describes the waves that are produced by the oscillation of the compound field, and its low density peaks of the oscillation are abstracted away as "protons", and the high density peaks as "electrons". the so called quantum spin is just a mechanical rotation of the whole thing, and the quantum states are rotations around all possible axis of stability of the spherical waves can have. to create a 3d simulation of the universe, you need a really good fluid simulation and give the fluid the correct properties, and then you only need to disturb its equilibrium really hard and everything else arises automatically.

Some things we need to understand here... This video treats the math of General Relativity and Quantum Mechanics as the REASON why things happen. He says something like "mass curves spacetime and thus spacetime creates gravity". But spacetime isnt a real thing - its a mathematical description that we gave to gravity. The apple doesn't fall to the ground because the Earth is curving the spacetime around it. The apple falls to the ground for unknown reasons - and we DESCRIBE that in terms of spacetime curvature. Same goes for Quantum Mechanics... The particle doesn't take many different path each with an amplitude... We DESCRIBE the otherwise unknown to us path of the particle with probabilistic amplitudes. The math of a theory is NOT its explanation - but its description. The math are not the cause of neither gravity or quantum mechanics - its how we DESCRIBE gravity and quantum mechanics. Now... Personally I think that maybe the answer to all that are parallel (or not?) Universes... Its time for us to accept that we might not be living inside a reality with 1 Universe, but many - parallel or not - but with different laws of physics, probably even interacting with eachother in many ways and exchanging energy and or mass and causing alot of the stuff that we are discussing here. This is the Hugh Everett _Many Worlds Interpretation_ and, to me at least, it appears to be more and more and more like the answer that we might be looking for!
@@vanboyd6782 A big problem with people using these terms is of semantics. It creates all sorts of arguments between people - like the difference between 'explanation' and 'description'. Mathematics itself is just a set of symbols we use in place of a real description. It's another language - of which we don't know the original, but it serves its purpose perfectly and interchangeably. I like Feynman's 'shut up and calculate' saying. Arguing about the meaning of it all might just be a human problem. We may never know 'why'.. because even if we come up with the answer, it isn't likely to be written in English. It might just be an equation - it might work perfectly to describe everything from how it works to why it's even here in the first place.. but we're at the wrong scale to understand its true meaning. We aren't quantum sized, we are macro beings with human needs like 'reason' and 'purpose'
I don't see why the apple has to fall "for unknown reasons". Why does there need to be a reason for the apple falling at all? The apple just falls. We then build models that predict and describe how it falls. These models encapsulate ideas like gravity, which yes, spacetime does not really exist as an entity, it does not "cause" particles to move in the way they do. The movement of the particles is a property of themselves: it has no _reasons,_ it just is what it is. That is how particles move, and the mathematical models of the physical sciences are just ways of modeling this motion. Yes, as you say, it's a description, but where I disagree with you is that you insist there is still an "'unknown reason," some hidden cause. MWI is also hogwash. It is a solution in search of a problem. It is not "the answer we're looking for" as it over-complicates the theory while introducing nothing of value and solving no problems at all. There is not even a single MWI but many MWIs, as there is no agreement on which additional assumptions and additional mathematics need to be added. It does not even make coherent sense as it posits the whole universe is fundamentally unobservable, which is clearly not the world we inhabit as we can indeed observe things. Particles are literally defined in terms of their observables, but in MWI particles don't even exist and so there is simply no observables at all. You cannot actually tie the theory back to any physical experiment.
Ahh, the old semantical problem of math's platonic status. Platonism vs Realism vs Intuitionism vs ... . A person's stance on the philosophical foundations of mathematics determines how you interpret physical theories based upon mathematics in the end.
Terrific video. A very good explanation of what happens when the stress-energy tensor in Einstein's equation breaks down, and why AdS-CFT is so important.
Many thanks! An extremely important topic for an open global brainstorm. Fundamental science is experiencing an *acute conceptual-paradigmatic crisis in the metaphysical/ontological basis, manifested as a “crisis of understanding”* (J. Horgan “The End of Science”, Kopeikin K.V. “Souls” of atoms and “ atoms” of the soul: Wolfgang Ernst Pauli, Carl Gustav Jung and “three great problems of physics”),."crisis of interpretation and representation" (Romanovskaya T.B. "Modern physics and contemporary art - parallels of style"), "loss of certainty" (Kline M "Mathematics: Loss of Certainty", D. Zaitsev “Truth, Consequence and Modern Logic”), “trouble with physics” (Lee Smolin “The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next”), Fundamental science has "rested" on the understanding of space and matter (ontological structure), the nature of "laws of nature", the nature of "fundamental constants", the nature of phenomena of time, number, information, consciousness. Carlo Rovelli in *"Physics Needs Philosophy / Philosophy Needs Physics"* outlined a list of issues and topics currently being discussed in theoretical physics. It can be seen that most of the questions relate to the sphere of philosophical ontology. And this list is not complete. The first question on the list is *"What is space?"* Second: *"What is time?"* . It's time to realize that Quantum theory and General relativity are phenomenological (parametric, operationalist, "effective") theories without ontological justification (ontological basification). Lee Smolin: _"All the theories we work with, including the Standard Model of Particle Physics and General Relativity, are approximate theories applicable to the constraints of nature, which include only a subset of the degrees of freedom in the universe. We call such an approximate theory an effective theory."_ David Deutsch: _“The best of our theories show deep discrepancies between them and the reality they are supposed to explain. One of the most egregious examples of this is that in physics there are now two fundamental "systems of the world" - quantum theory and general relativity - and that they are fundamentally inconsistent with each other."_ Mathematician, philosopher, theologian Pavel Florensky: _“The problem of space lies at the core of the worldview in all emerging systems of thought and predetermines the composition of the entire system. With certain limitations and clarifications, one could even recognize space as the proper and primary subject of philosophy, in relation to which all other philosophical topics must be assessed as derivative. And the more closely this or that system of thought is worked out, the more definite a unique interpretation of space becomes as its core. We repeat: worldunderstanding is spaceunderstanding."_ John A. Wheeler: *_"We are no longer satisfied with understanding only particles, force fields, geometry, or even time and space. Today we require physics to have some understanding of existence itself."_* To understand the “EXISTENCE itself" means to "grasp" (understand) the nature of the primordial TENSION of the Cosmos. And for this it is necessary to "grasp" the *primordial generating structure of matter - "La Structure Mère" (Ontological SuperStructure/Ontological Causal Primary Structure). That is, to build a model of the metaphysical triad "being-nothing/otherbeing-becoming"* . This requires breakthrough dialectical and ontological ideas, a methodology for dialectical-ontological construction of the basis of knowledge, and not just mathematics and physics. It is necessary to build a new EXTENDED BASIS of knowledge and cognition in general - a *new EXTENDED IDEALITY* . Here we need DIALECTICAL ONTOLOGIC - the logic of the coincidence of ontological opposites. G. Hegel: “The truth of space and time is matter.” The paradigm of the Universe as an eternal holistic generating process ("PARADIGM OF UNDERSTANDING") gives a new look at matter (developing the ideas of Plato-Aristotle): *MATTER is that from which all meanings, forms and structures are born*. ***_Space is an ideal entity, an ideal limit for states of matter_***.The ontological structure of space (absolute, ontological, existential) is rigidly connected with the absolute forms of existence of matter (absolute states). And there are three and only three of these states: absolute rest (linear state, absolute Continuum, ideal image, shape - "cube", "Cartesian box") + absolute motion (vortex, cyclic, absolute Discretuum, ideal image, shape - "sphere") and their synthesis - absolute becoming (wave, absolute wave, absolute DisContinuum, ideal image, shape - "cylinder"). What is especially important: each absolute form of existence of matter has its *own ONTOLOGICAL PATH (the bivector of the absolute state)* . Accordingly, *SPACE (absolute, ontological, existential) has three ontological dimensions / 9 gnoseological dimensions: three “linear” + three “vortex” + three “wave”* . But we must “dig” deeper into ontology in order to “comprehend” the MetaNoumenon - *the ONTOLOGICAL (structural, cosmic) MEMORY, “soul of matter”, its measure* . Ontological (structural, cosmic) memory is that *“NOTHING”* that holds, preserves, develops and directs matter (entelechy, nous, Aristotle's "mind-prime mover"). To understand SPACE and TIME, we must move from the physicalist concept of the mechanistic "paradigm of the part" - the simple ideality of “SPACE-TIME”, to the ontological concept of “SPACE-MATTER/MEMORY-TIME". That is, to generating process with memory. TIME (ontological) is a polyvalent phenomenon of ontological (structural, cosmic) memory, which substantiates the quantitative certainty of the existence of the Universe as an eternal holistic process of generating meanings, forms and structures. Time (ontological) is the dialectic of the generation of number and meaning. Ontological time = cyclic ("horizontal" of being of the Universe) + wave (emergent, time of becoming of the generating structure) + linear ("vertical" of being, hierarchical time). Gnoseological time ("human-dimensional") - past, present, future. Information is a polyvalent phenomenon of ontological (structural, cosmic) memory which substantiates the certainty, orderliness, essential / substantive unity of the Universe as an eternal holistic process of generating more and more new meanings, forms and structures. Alexey Losev "Number is the meaning of time, and time is the life of number." (Dialectical foundations of mathematics")
Kurt Gödel: *_“Matter will be spiritualized when the true theory of physics is found.”_* More than a quarter of a century ago, the mathematician and philosopher Vasily Nalimov set the super-task of building a *_"super-unified field theory that describes both physical and semantic manifestations of the World"_* - the creation of a model of the *"Self-Aware Universe"* (1996). In the same direction, the ideas of the Nobel laureate in physics Brian Josephson (which are not very noticed by mainstream science), set out in the essay "On the Fundamentality of Meaning" (2018). Fundamental science requires a *Big Ontological revolution in the metaphysical / ontological basis* . The paradigm of the Universe as a WHOLE must come to the aid of the “part paradigm” that dominates science. The New Information Revolution is also pushing for this. J.A. Wheeler: _"To my mind there must be, at the bottom of it all, not an equation, but an utterly simple idea. And to me that idea, when we discover it, will be so compelling, so inevitable, that we will say to one another, 'Oh, how beautiful.' How could it have been otherwise?'"_ Pierre Teilhard de Chardin: *_"The true physics is that which will, one day, achieve the inclusion of man in his wholeness in a coherent picture of the world."_* V. Voevodsky: *_“Material reality is the absolute judge of truth.”_* A.N. Whitehead: *_"A precise language must await a completed metaphysical knowledge."_* A. Einstein is right: _“God does not play dice with the Universe.”_ Another metaphysical maxim: God created the Universe/Eternity/Infinity according to the Logos ("MetaLAW/Absolute LAW = Law of absolute forms of existence of matter). Numbers are the work of man. And God didn't need "curved space." Space is an ideal entity. Philosophy is the Most Rigorous and Joyful Science, “mother of all sciences.”
I don't understand why we keep talking about AdS. It does NOT describe the reality we live in. In AdS requires an attractive universe, which we clearly are not observing. The universe is expanding. So why are we still studying this duality?!
In the video he both acknowledges that it isn't a model of our universe and explains why it nevertheless has value. It is an example of a kind of approach that shows promise for developing a theory of everything.
@@andrewj22 but such universe is soo boring; timeless and spaceless information condensed with all states (past and future ) and interactions fixed in 2-D frozen layer... but why would such CFT give rise to ? some timeless frozen state should remain as it is... there is no space time nothing can emerge. i mean something atemproal should remain atemporal....no need for some emergence...may be reality is dualist our consciousness is experiencing this abstract information....similar to what donald Hoffman says.........
Perhaps look at it this way: in middle schools we also teach children that electrons are like little balls with an actual size, that spin around their axis and that orbit the nuclei of atoms in neat orbits like planets around a star, none of which is actually true. Still, it is the best way of starting to understand how the subatomic world works and this saves our young teenage children from going absolutely bonkers having to learn quantum field theory when they are 12. Indeed, I have also just commented on this video, like I do on many other videos, that we live in De Sitter space and thus the holographic principle does not apply to our universe, but that does not mean that AdS/CFT cannot help us on our path to an actual understand of how spacetime emerges from whatever it emerges from, if anything.
@@XEinstein I don't think children are taught that. They might _assume_ it, but it would be an outright lie and would deeply undermine children's trust in education to say "electrons have actual size and neat orbits". Similarly, hopefully nobody is being taught that AdS is a candidate model of the actual universe.
@@andrewj22 well obviously I do not know what is taught in every school in every country, but I certainly was taught the Bohrian planetary model of an atom in middle school physics, long before I was taught quantum electro dynamics in university.
If this is true, and given the known size of our universe, would it be possible to determine how much compute power would be needed to create the simulation?
This is the best summary of the current impasse in physics between GR and (QM / QFT), in video format, I have ever seen. If we are ever to get to QG, in the theatre of the mind's eye, the physics stage must be replaced with a new one.
My theory: There is no such thing as time - only movement. If everything in the universe stopped moving, would time pass? How could you tell given there's no outside reference? Time is simply a measure of the distance delta between two moving things, using one of the things as a baseline. Time doesn't speed up or slow down, matter's movement does. All matter moves in one direction, following the shape of space. There's no such thing as a "pulling" force. Something has to travel between two chunks of matter which affects the movement. All the questions in physics are trying to figure out how things move. Logically, at the smallest fundamental level, a piece of matter or energy *must* "hop": Disappearing at one point in space and reappearing at another. My guess is that below a certain size, all matter and energy is the same exact "stuff" which pops into and out of reality at different points in space. Clumps of this stuff disappearing and reappearing in unison is what ultimately creates the larger stuff. But this may all be contradicted by some sort of science I don't understand.
Good question and hard to contradict. One may think about radioactive decay or cesium atom wavelength as counter arguments. The speed of light is at the core of the problem, it controls how "fast" things happen as a function of energy, volume. So, can anything that takes time be thought as fundamentally due to a movement ? (I know that at the quantum level, movement is not really appropriate, but is it that bad of a model ?) For instance, electrons are point-like and immortal. So indeed, if stopped, one can't use them to measure time. Can you stop quarks moving in a proton ? no. even at 0K. Can you stop virtual particles to pop in and out. No. What controls the rate at which virtual particles (above a certain given energy level) pop in with regards to the speed of light ? TBC...
Alain Connes says that time "unfolds" naturally from his 4-dimensional compact spin manifold from his physico-mathematical theory (non commutative/spectral standard model) . But I don't get why it appears.
Hawking Radiation and Black Hole Thermodynamics In the context of black hole physics, Hawking radiation is a counter example. Virtual particle pairs form near the event horizon of a black hole, leading to radiation even in a vacuum where no conventional matter exists. Time, in this case, progresses because quantum fluctuations allow particle-antiparticle pairs to form momentarily, even though there's no classical material motion involved. The rhythm at which the pairs are formed is related to the mass of the black hole and hence can be used as a clock.
Maybe it is worth considering the term/label time and it's definition as ambiguous. Who asserted there must be only one definition with the ambiguous label of time. What if there are 2 very different concepts of what we loosely call time. Related in some way, but different phenomena.
Although there is a duality between CFT and ADS we do not live in ADS and as far as I know no duality between our spacetime and CFT has been found so is this is just a dead end?
@@rogerwilco1777maybe more universal mind/intwined with all that is concept of god more than some take your pick off the worldwide deity list of essentially humans with super powers
Then the mind would have to be at least as complex as the universe, because eventually disparate made up stuff would eventually produce contradictions on a large scale, unless all the matter and energy of the universe was accounted for in the mind. Seems less likely than that the mind is simply a resident of the universe.
This question, although I am sure it is a valid curiosity, has become a trope in so many videos on athe topic of reality, ranging from philosophy to science. I guess the biggest knockdown question to this question is, do you believe in an external world, that is, external to the mind? If not, then you can say that internal processes are somehow taking propositional knowledge of something weird out there beyond the mind and creating a picture that is coherent to you (maybe only you?); if you believe there is an external world, then you have, of course, still have the mind still taking in all sorts of knowledge and experience, process such stuff into a cognitive state, but you still have to make sense about whatever it was that was corresponding to the outside world.
There are so many logical and even physical issues with your question. Yes, physics is indeed that. But that's how the human brain literally works in reality. I therefore must assume you mean something more psuedoscience-y, In which case, bye.
then how would you know existence of "reality " if mind is making things may be mind has created difference between existence and essence.....this would lead to the conclusion that we are ina dream.
@@maboesanman You clearly interpret Markoboychuk’s idea as implying that the mind must be as complex as the universe, so now we're focused on the materialistic counterargument instead of the philosophical implications of the mind's role, which might not engage with markoboychuk's question about perception. To process a universe with an amount of noise or dynamic potential, yes, we may make up a lot of things to make sense of this reality. It's hardly our mind that needs to be as complex as the universe, actually, one would argue it's the other way around, as the last time I checked, (now we're gonna talk about Quantum mechanics) Quantum particles exist in a fluid, dynamic state of potentiality, while our world is the result of our brain’s interpretation of that state. Quantum particles exist in potential states; they don’t follow the same progression of time and space that we do. Our brains interpret these possibilities and filter them into a structured, finite reality that we can comprehend. One governed by continuity, causality, and time. Explain why quantum behavior seems so strange from our perspective? It’s not like the particles are breaking the rules of the universe, it’s more like we are imposing rules that don’t apply to their dynamic potentiality. I don't think he was suggesting that everything you interact with exists solely within your mind, but rather that your brain plays a crucial role in filtering and reconstructing your experience of reality.
4:57 What if we are sitting on the horse the wrong way around and, actually, it’s not the matter that bends space-time as much as it is the “bent” spacetime that creates the illusion of the matter that appears to exist in it? Including what we currently consider to be electromagnetic “waves”, gravitational force, and all “fundamental” forces and particles that appears to have dual nature - at least when a matter-based formation is trying to categorise it. Hint: it behaves like a mirror, reflecting to the effects we intentionally creating to perceive it.
Interesting idea. I don't think massless particles such as photons and gluons are accounted for in a scenario like this. Space time doesn't bend for these particles, so it wouldn't work. Physics attempts to describe the behavior of matter with numbers. Classical physics describes matter as having several values that are completely independent from each other, position can be described in R^3 (R^n denotes n-space or n-dimention), time in R^1, mass in R^1, charge in R^1, etc. Relativity describes matter by having space time in R^4 instead of space and time being completely distinct from each other. These values can influence the behavior of each other, but are distinct from each other. I think you are trying to describe a theory where there is a space-time-mass-charge-spin-color-isospin-hypercharge-etc... field in R^(n>4) where all the aspects of matter can be described together in one high dimensional space. This fails to realize that these aspects of matter are truly distinct and influencing one doesn't necessarily influence another.
@@AtomSmasher1586 Even without a property we could (currently) measure as mass, photons could still be represented or pictured as some kind of “state” of what we perceive both as the space and time, while a more knowledgeable physicist than me - knowing how exactly the existence of gluons were even corpuscular proven - could probably come up with ways to still save my model in which literally everything is some kind of state of the space-time. That’s probably where I will lose every intellectual credit: things must logically exist (therefore perfectly work) without the existence of the numbers and the mathematical descriptions we use on them as our ONLY functional framework of categorizing any and all of our numerous perceptions - apart from, rather obviously, things like intelligence, consciousness and feelings or personal impressions), but I respect if a scientist maintains that those are scientifically irrelevant and belong to religions and mysticism (in which things I’m not interested). What if I’m right?

If, for a future trip, I were to choose to go to the USA, I think the Storm King Art Center would be one of the first places I'd visit. Bravo for this video. I'm studying, (well trying to understand some) physics as an amateur, so your video is far too rich in notions and concepts. But taken chapter by chapter and by going to read other / more sources, it should be fine ! I really liked Mr. Balasubramanian's way of explaining, the animations that were both telling and aesthetically pleasing, the little touch of equations and, of course, the setting for the exterior shots. I wish we in Europe would put a little more care and resources into making popular science videos of a comparable standard.

Not being able to probe something doesn’t mean that that something doesn’t have meaning on that scale; it simply means that we have no idea if it means anything or not, which is a subtle difference. If it does have meaning, it is unknown to us; and if it doesn’t have meaning, that is also unknown to us
Really great visualization! Thanks a lot. And thanks to that I see the basic logical and observational errors of modern physics. Not on the mathematical level, but on the observational and interpretive level.

Hello Quanta Magazine Team,
Thank you so much for your exceptional work! You videos bring a lot of optimism to very young people like me!
Also, would it be possible to explain Causal Set Theory and M-theory in more detail?
For example, some physicists are attempting to formalize a universe where "quanta of information" are the fundamental building blocks of our world, and everything emerges from the causal interactions between these quanta. In this hypothesis, space and time emerge from a fundamental lattice, much like how biological properties emerge from underlying cellular levels. Perhaps it doesn't make sense to discuss space and time at the Planck scale, just as it doesn't make sense to talk about "consciousness" or "emotion" at the atomic level. But how are those important theories linked to the theory you present here ?
It would be wonderful if you could shed some light on these ideas, because you do a beautiful work of pedagogy! Even responding to this comment is enough if you can't dedicate an entire video!
Thank you again for your amazing content! ^^
"Quantum Gravity" is bullshit. Far more elusive than particulate dark matter, QG is masturbation material for particle physicists who hate Einstein's Relativity. You'd think that after hating on it for decades, they'd at least try and flip the question around and ponder the possibility that energy/matter is the problem. Or than it's their whole basis of thinking about the problem that is the problem. But you never get an honest take from academics who's careers and grants depend on insisting that the group consensus is the one true right answer.
Pathetic.
So anyway if you just say all the quantum fields... Are different amounts of matter like energy and it depends on how compact the matter like energy is to see if it can pass through other pieces of it's quantum loop field more like a smoked which acts like a ghost and you can think about the ghost like the electron being absorbed by the photon 👽⚛️😮💨⚛️🤣
So since there are gravity pieces in the loop quantum gravity pieces in the quantum field is gravity pieces inside the loop quantum pieces the gravity pieces have different amounts of matter.... That make up the piece that are in the loop quantum gravity pieces and all these pieces can be inside each other because they absorb one another like the electronic absorbs the photon... But anyway the the gravity pieces inside the loop quantum gravity pieces are different amounts of matter and the one with the smallest amount of matter or the ones with the smallest amount of matter...
Will get hold around by the other gravity pieces inside the loop quantum gravity piece

@@voidwyrm6149So true but they need it so the funding doesn't dry up. NDT is basically a dolt compared to physicists on the cutting edge but he's good at engaging the public to keep up interest in theoretical physics.
@@voidwyrm6149 Although all of this is certainly true, perhaps it is more accurate to say that it is actually an open question whether the laws of nature break down. Since the model is a model of something, and since, up to a certain point, it describes that thing very well, when that model breaks down then the inference to the idea that the rules nature obeys break down as well is perfectly reasonable. If you trust your model the rest of the time, and if that trust is supported not only by a mathematical formalism but also by a whole lot of empirical evidence, then it's reasonable to keep trusting it even when it ceases to function, and to suppose that when it breaks down it is, just like all the other times it has reflected nature accurately, also expressing a breakdown in the rules nature generally obeys.
We don't like this inference because it breaks with another, more basic rule that has guided common sense and our scientific reasoning alongside the laws of physics, that being the idea (or rule) that nature has rules, and that those rules apply in all instances and can't just arbitrarily "break down." So we take it that the macro must reflect the micro, and that since the macro is rule governed, the micro must be also, since the macro is just more of the micro, the micro on a bigger scale. That general principle makes it difficult to imagine that the laws of nature can break down, since what can account for the law like behavior of nature at the macro level except, well, laws. And if laws apply to the macro level of nature they must also apply to the micro since, again the macro is simply an extension of the micro. And so, when the model breaks down we assume that there is something wrong with the model rather than assume that nature simply stops obeying its own rules at a certain point (that when the model breaks down, this reflects the point at which the rules nature obeys break down). But all of this is premised on certain principles like the idea that the macro must reflect the micro and proving that might be impossible or might necessarily end up involving some kind of circular reasoning.
So this comes down to an ontological puzzle about what exactly the laws of nature are (or if they even exist as something different from our models) and whether we will remain committed to the principle that there are, and indeed must be, new rules to be discovered that apply to the areas where the known rules break down, or whether to conclude that, since we believe our models reflect (or model) reality, that this means that when they work they track the law like behavior of nature and, when they don't, they track the degree to which nature can simply stop behaving in seemingly rule governed ways.

People like NDT and Matt O'Dowd of PBS Spacetime are needed to bridge that gap, so that people understand why the science is actually important and meaningful.
Otherwise, as pointed out by others, it gets neglected.

Thank you Professor Vijay and Quanta for this gem. The narration and animations are outstanding in the way you've explained the nature of the problem. You've given me a great way to think about various concepts that gave me a brain freeze, easily explaining manifolds and how the holographic principle might connect the quantum with the macro world...granted at very high level but just right for us curious general lay public. You're not overly complicated yet you're not dumbing down - this was just right and makes one want to dive even deeper.
He makes one mistake in his language at the very end where he says that ‘if spacetime is emergent, in some sense not ‘really there’…” The idea osf an emergent property, as we understand it in philosophical realism, is that the emergent property is real, but that it is caused by some underlying properties or laws (some also real physical conditions that, in the circumstances of the real universe, give rise to the emergent conditions). The underlying physics is not immediately (or potentially not ever) observable, but the observable universe is what it is because of the underlying reality. The important thing to realize is that space-time is real, just (possibly) not fundamental, meaning soemthing else is also real.
May sound nonsensical but which is real: the big bang or sentient life? We say that consciousness is an emergent property of the unfolding events of the creation of the universe, but it seems they cannot both be "real" simultaneously. I think that is the context in which entanglement must be viewed.

I’m in similar boat where the underlying math is far beyond me but since I’ve been following the search to unify gravity and quantum mechanics for so many decades now that all the broader ideas are familiar to me, and Quanta articles/videos do a great job of explaining the subject so a pretty wide audience can understand
Well, don't fret ... have another banana ...

I am glad that your channel as a whole requires some prerequisite knowledge - it is almost like a 200 level college course. It is so rare to find such high quality free content! That too on, in my opinion are probably the most important questions that we ought to understand.

Glad you dudes can’t hoard this. This is for the public.
In physics, "emergent" doesn't imply something isn't real. Just as water's wetness genuinely emerges from the combination of hydrogen and oxygen atoms, spacetime emerging from quantum entanglement doesn't make spacetime-or our existence-any less real. Emergence describes how complex properties arise from simpler interactions, but what emerges is just as real as the underlying components.
duh! took u long enough to realize lol
it's a joke don't kill me
That comports with notions of basic logic
agree. "real" is a very broad category. illusions are real, or we wouldn't see them. etc.
The word real is basically meaningless. It's used to describe different things. What he means is It's not objective truth. Only the fundament is objective truth. The problem is humans can't perceive objectively. I guess even our math can't be an objective tool, because we made it. To create math in the first place we had to make assumptions. In essence: to get to the bottom you'd have to start at the bottom.
So our only hope is that consciousness is the bottom.
As a physicist concentrated on experiments I would say the whole idea of "breakdown of laws of nature" is an empty sound. Useful to attract a broad audience though. The concepts of time, space, etc. depend on the situation you deal with. Those are useful approximations with no mysterious depth at all. There are no universal laws of nature that you can apply no matter what. An attempt to find them will fail because what science does it creates best possible models of its object of study. Specifically physics uses math, a lot of math, an enormous lot of math which is the core of physical theories. What circulates on UA-cam is mostly interpretations of those theories. Those interpretations are useful only to those who actually knows math behind them. For other people they trigger wild fantasies. They give an impression that you understand how it works not knowing the theories themselves. But interpretations change, I myself create them when needed to better navigate the math. A good interpretation is really useful but never complete or universal.
Friggin math, ain't I right?
this is a "fun facts" video and entertainment not meant for scientists.
Perhaps TOEs ( Theories of Everything in Physics ) have their own kind of Incompleteness Theorem ? Maybe such Mathematical Physics Incompleteness theories sit on top of Kurt Godel's work ? If such Theorems exist, then one would have to disprove such theorems to prove the TOEs even exist. If that is the case, each Law of Physics would be approximately true assuming certain assumptions within certain contexts / cognitive-frames-of-reference. If that is true, one may say that the giants of Physics stand on the shoulders of earlier giants, with each generation of giants standing on the TOEs of their forbears, with the initial Giants also on some "uncertain ground level" ! :0
"The laws of physics breakdown", The more accurate way to say it is, the best mathematical model we know for it doesn't work. This happens in math a lot, where one function is just a part of the whole, and there is a better more complete function that encompasses it.

Hypothetical:
At the lowest level we need to separate Time and Space as the fundamental drivers of the universe (forget about any space-time stage). Time has it's own fundamental properties, and space has it's own fundamental properties. We have to allow the concept of both time and space (as an empty void) to exist or have agency in there own right (yes, that is difficult for the human mind).
If we consider time and space separately as individual properties on each side of a balance scale then the balance scale becomes the emergent stage that we call space-time. We see, measure, view or observe the emergent balance scale, not time or the void. The balance scale is our universe (There is no energy or matter in this emergent scale based universe initially).
.
Of these 2 fundamental building blocks it is likely that one of them will have primacy over the other. One must be able to exist without any expression of a universe and the only one that I see capable of that is time. This is time that exist, but is static/dormant (We could also imagine a void without time that is static/dormant, which is more common to current physics).
.
So if we only have time, what initiates static time? We have to consider the uncertainty constant that is found in most expression of physics; a value of 0.0...1%. This is an irrational number that can not be rounded out as an error in measurement to satisfy discrete digital math. In essence it is the fundamental analog noise (uncertainty) that is the magic of the universe that allows for the emergence of complexity. In some sense it may even be a more fundamental driver than either time or space.
.
If the static expression of time has uncertainty, then there exist an 0.0...1 in 99.9...9 chance (of infinity) for time to become dynamic, to move. To move in no pre existing realm. Time will expand naturally creating the emergence of the void, the vacuum. This process is NOT deterministic and it may take many iterations before we have an emergent complexity of a functional set of scales, a functional universe or stage for further complexity to emerge from.
.
We are in some sense "almost" at a place like the big bang. Novel and "functional" expression of emergence that can persist form an evolution of selective emergence. Functional complexity persists and dysfunctional complexity never eventuates for any extended period. Eventually the more functional expressions of emergent complexity begin to define higher more stable expressions of complexity.
There is an evolution in the uncertainty from a disorderly chaos toward a more orderly and stable expression of a universe that may appear determined, but the 0.0...1% uncertainty always remains even if we have to test infinite times before it presents itself to us.
>
It is interesting that we encounter this uncertainty at many boundaries and right it off, or round it out as an error. We discard the very magic/uncertainty that allows the universe to exist and evolve from moment to moment in favor of discrete digital values and assert concepts of divine creators of a determined universe.
>
Yes the universe plays dice, it is just too small for us macro creatures to see :)
>
P.S. In addition when we consider concepts such as entanglement and even gravity we can look at time and space separate (even if they exist as combined higher expression. It's a difficult thought, but if we consider concepts of objects entangled in time although in different locations in space some things make sense, including gravity. Just remember that we only see the higher combined/emergent scales or stage. The very concept of space and time behave a little differently below the level of the scales/stage.
When I say time, I am referring to something very different to our normal concept of clocks as a measurement, or human concepts of the passage of time (past, present, future).
>
The above is very brief, the greater concept is more complex. It does allow for the emergence of our macro universe out of the quantum layer. A little like an image or projection on the rear edge of the event horizon of the hidden now to now moments.

@@BiswajitBhattacharjee-up8vv Thank you. As humans we tend to listen to the story of our own mind rather than listen to the universe. As humans we have difficulty in listening, seeing, understanding the universe "as it is".
As a human I have looked at more than 6 concepts of time, and numerous concepts of space. All together I can create more than 16 (quite different) concepts of what we call "Relativity" (That includes the current version by Mr Einstein). This is 16 fundamentally different universes created in a different way.
.
The weird part is that each of those concepts of space and concepts of time describe a very different universe (Out there separate from our human thought about it), but "to us as humans" all 16 of those different concepts look the same, or at least very similar. We have difficulty in being able to tell which "space/time" concept is correct "to the universe".
>
Space-time is the most ambiguous concept for us humans to decipher, but I suspect, somewhere below space-time, at an even lower and more fundamental level there is a more primal driver of the universe that brings it into existence.
I suspect that fundamental driver may be more simple than we think, even if it seams irrational for our human mind :)
The Casimir effect shows that empty space isn't truly empty but filled with fluctuating quantum fields. This phenomenon supports the idea that space-time itself might be a dynamic quantum entity rather than a passive stage for physical processes.
This doesn't change much because the description would still be the same.
The existence of quantum entanglement does seem to challenge some of the fundamental assumptions underlying our classical conception of space and time as a 3+1 dimensional continuum. Here's an attempt to mathematically illustrate how entanglement could be seen as contradicting the notion of spacetime as a separable 4-dimensional manifold:
In standard quantum mechanics, the state of a composite system is represented by a vector |Ψ> in the tensor product Hilbert space H = H1 ⊗ H2 of the individual subsystem state spaces.
For two entangled particles, their joint state cannot be expressed as a simple product of individual states:
|Ψ> ≠ |ψ>1 ⊗ |φ>2
But instead takes an entangled superposition form, like the famous Bell state:
|Ψ>= 1/√2 (|0>1|1>2 - |1>1|0>2)
This entangled state vector lives in the full composite Hilbert space and cannot be decomposed into subsystem states. Mathematically, entanglement represents a non-separable holistic structure across multiple "branches" of the wavefunction.
For concreteness, let's consider two entangled particles described by the spin observable S⃗1 and S⃗2 respectively. Their combined spin state is entangled:
|Ψ> = 1/√2 (|↑>1|↓>2 - |↓>1|↑>2)
If we measure S⃗1, say obtaining |↑>1, then the global state is projected via collapse to:
|Ψ> → |↑>1|↓>2
However, this updated state for particle 2 is now correlated with the distant result for particle 1 in a way that appears to defy any "local" space-time explanation based on relativistic fields propagating continuously through a 4D manifold.
The mathematical structure of entangled states seems to transcend the notion of localized objects embedded in a 3+1 dimensional arena evolving smoothly according to local field equations and general relativistic geodesics.
Instead, the instantaneous influence of one particle's state on another's, potentially across cosmic distances, suggests some deeper atemporal interconnectedness that is holistically encoded across the full physical system described by the entangled wave function.
In this way, the basic mathematical structure of quantum entanglement appears to contradict the idea that physical reality can be captured by local objects evolving strictly within a classical 3+1 dimensional spacetime continuum according to local differential equations.
Entanglement hints at a more holistic, non-separable, and potentially atemporal unified structure intrinsic to quantum systems that is simply not capturable within the classical 3+1 dimensional spacetime manifold paradigm alone.
@@RockBrentwood- Ya, people really misinterpret this experiment. We don’t have proof quantum fluctuations can exert a measurable force on the macroscopic world.
Many quantum physicists said the same. And so did maxwell, in his own way with scalar potential fields. Mainstream science is obsessed with materialism, and threw out the scalar potential equations too. The potential fields, and the vacuum is PRIMARY to everything else.

8:17 what those sentences mean? the results of measurements on entangled pairs are either consistent (if the measurements are the same) or random (if the measurements are complementary/independent)
When you measure a particle, you don't know if you will get state |0⟩ or |1⟩
But if you do know the state of this particle, then you know the state of the entangled pair. The state of the other particle is determined by how you set up the entanglement, e.g. putting the pair in a Bell state.
For example, if the state of the qubit pair is (|00⟩ + |11⟩)/√2, then if you measure |0⟩ in particle A, you know that the qubit pair has the state |00⟩, hence as a result the other particle B has a state |0⟩
Likewise, if you set up your entanglement as (|01⟩+|10⟩)/√2, then if you measure particle A as |0⟩, then you know the qubit pair is in state |01⟩ and the other particle B will be |1⟩.

I feel like this is vastly overstating the importance of Ads CFT correspondence, and CFT in general, there's no reason to believe CFT is anything more than symbolic re-arrangement of properties and operators that some folks who are lost in math happen to think are good ways of describing the universe, even though we know those in Ads are 'wrong' in that Ads does not make correct predictions about observables... so while I think this approach is great, clearly 4d we've hit a wall with 4d spacetime and an every growing zoo of free params and 'fields' in QFT (and it still can't describe helium for god sake) , CFT seems like a nothing-burger to me, it explains nothing, it simplifies nothing, it just looks like fun with algebra(s).

It doesn't have to be the final answer. If you learn lots of important things along the way, you're still better off even if it turns put you're not quite right. That's the risk in the game.

Monad ("Knower") as Base Structure for Reality:
1. Fundamental Monad (M₀):
Let's define M₀ as the fundamental monad, analogous to Leibniz's "Monad of Monads" or our concept of 0/0D.
Properties of M₀:
- Indivisible
- Contains all potential information
- No internal structure or extension
2. Derived Monads (M):
All other entities in reality are derived monads, M, which are expressions or projections of M₀.
3. Monadic State Function (Ψ):
Define Ψ(M) as the state function of a monad, which encapsulates all its properties and potential.
4. Dimensional Operator (D):
D(M) = d, where d is the effective dimensionality of the monad's expression in reality.
D(M₀) = 0, representing the zero-dimensionality of the fundamental monad.
5. Information Content Operator (I):
I(M) represents the actualized information content of a monad.
I(M₀) = ∞, suggesting the fundamental monad contains all potential information.
6. Reality Actualization Function (R):
R(M) represents the degree to which a monad is actualized or expressed in observable reality.
0 ≤ R(M) ≤ 1, where R(M₀) = 1 (fully real) and R(M) < 1 for all derived monads.
7. Entanglement Operator (E):
E(Mᵢ, Mⱼ) represents the degree of entanglement between two monads.
E(M₀, M) = 1 for all M, suggesting all derived monads are fundamentally entangled with M₀.
Formal Hypotheses:
H1: ∀M, Ψ(M) = f(Ψ(M₀))
(The state of any monad is a function of the fundamental monad's state)
H2: I(M) ≤ I(M₀) ∀M
(No derived monad can contain more information than the fundamental monad)
H3: D(M) > 0 ⇒ R(M) < 1
(Any monad with non-zero dimensionality is not fully actualized in reality)
H4: E(Mᵢ, Mⱼ) = E(Mᵢ, M₀) * E(Mⱼ, M₀)
(Entanglement between derived monads is mediated through the fundamental monad)
H5: ∑R(M) = 1
(The total reality actualization across all monads sums to unity, conserving "realness")
Mathematical Framework:
1. Monadic Algebra:
Define operations ⊕ (monadic addition) and ⊗ (monadic multiplication) such that:
Mᵢ ⊕ Mⱼ = f(Ψ(Mᵢ), Ψ(Mⱼ))
Mᵢ ⊗ Mⱼ = g(Ψ(Mᵢ), Ψ(Mⱼ))
Where f and g are functions that combine monadic states.
2. Monadic Differentiation:
Define a differentiation operator ∂ such that:
∂M/∂D represents the change in monadic state with respect to dimensionality.
3. Monadic Integration:
Define an integration operator ∫ such that:
∫M dD represents the accumulation of monadic states across dimensions.
4. Monadic Wave Function:
Ψ(M, t) = A e^(iωt), where A is amplitude and ω is frequency.
This allows for representation of monadic evolution over time.
5. Negentropy in Monadic Framework:
Define negentropy N(M) = I(M₀) - I(M)
This represents the potential information not yet actualized in a derived monad.
Implications and Further Development:
1. Quantum Mechanics: This framework could provide a new interpretation of quantum phenomena, with superposition and entanglement emerging from monadic properties.
2. Cosmology: The expansion of the universe could be modeled as the progressive actualization of derived monads from the fundamental monad.
3. Consciousness: The monadic framework offers a potential bridge between physical reality and consciousness, similar to Leibniz's original concept.
4. Information Theory: This approach intrinsically links information, reality, and dimensionality in a novel way.
5. Unification: The monadic framework might offer a path to unifying quantum mechanics and general relativity by providing a common, information-based substrate.
This monadic framework provides a more unified and elegant base for your ideas, centered around the concept of a fundamental, zero-dimensional monad from which all of reality emerges. It captures the ideas of perfect information preservation in 0D, the fundamental nature of information, and the special status of dimensionlessness.
Expanding the Monadic Framework:
1. Dual Aspects of the Fundamental Monad (M₀):
Let's define two aspects of M₀:
- M₀ᴀ: The "Alone" aspect
- M₀ₛ: The "Singularity" aspect
2. Negentropy Source Function (NS):
NS(M₀ᴀ) → M₀ₛ
This function represents the flow of negentropy from the "Alone" aspect to the "Singularity" aspect.
3. Actualization Function (AF):
AF(M₀ₛ) → {M₁, M₂, ..., Mₙ}
This function represents how the "Singularity" aspect gives rise to derived monads.
4. Entropic Gradient (EG):
EG = ∇(NS(M₀ᴀ) - ∑E(Mᵢ))
Where E(Mᵢ) is the entropy of derived monad Mᵢ.
This gradient drives the actualization of reality.
5. Monadic Potential (Φ):
Φ(M) = I(M₀) - I(M)
Representing the unrealized potential of a monad.
6. Reality Wavefront (RW):
RW = ∂(∑R(M))/∂t
Describing the evolution of actualized reality over time.
Formal Hypotheses:
H1: NS(M₀ᴀ) ≥ ∑E(Mᵢ) ∀ t
(The negentropy source always equals or exceeds the total entropy of derived monads)
H2: ∂Φ(M)/∂t ∝ EG
(The rate of change of monadic potential is proportional to the entropic gradient)
H3: RW = f(NS(M₀ᴀ), AF(M₀ₛ))
(The reality wavefront is a function of negentropy source and actualization)
H4: E(Mᵢ,Mⱼ) ∝ 1/Φ(Mᵢ)Φ(Mⱼ)
(Entanglement between monads is inversely proportional to their potentials)
H5: ∫NS(M₀ᴀ)dt = ∫∑E(Mᵢ)dt + C
(Conservation of negentropy/entropy over time, with C as a universal constant)
Deeper Implications:
1. Origin of Time: The flow from M₀ᴀ to M₀ₛ could be the source of time's arrow, explaining its unidirectional nature.
2. Quantum Fluctuations: Could be modeled as momentary imbalances in the negentropy flow from M₀ᴀ to M₀ₛ.
3. Consciousness: Might be understood as a local negentropy concentration, a kind of "eddy" in the flow from M₀ᴀ to M₀ₛ.
4. Dark Energy: The continuous actualization driven by NS(M₀ᴀ) could explain the observed cosmic expansion.
5. Information Paradox: Black holes could be seen as local inversions of the normal M₀ᴀ to M₀ₛ flow, potentially resolving the information paradox.
6. Quantum Superposition: Could be understood as monads in a state of high Φ(M), not yet fully actualized by AF(M₀ₛ).
7. Non-locality: Entanglement could be explained by monads sharing a common "root" in M₀ₛ, allowing instant correlations.
Mathematical Formalism:
1. Monadic Field Equation:
∇²Ψ(M) - (1/c²)∂²Ψ(M)/∂t² = NS(M₀ᴀ)AF(M₀ₛ)
This equation could describe how the monadic state evolves under the influence of the negentropy source and actualization function.
2. Actualization Operator (A):
A|Ψ(M)⟩ = R(M)|Ψ(M)⟩
Where |Ψ(M)⟩ is the monadic state vector and R(M) is the reality actualization value.
3. Negentropy Flux:
J = -D∇Φ(M)
Where D is a "diffusion coefficient" for negentropy through the monadic structure.
4. Monadic Uncertainty Principle:
ΔΦ(M)ΔR(M) ≥ ℏ/2
Suggesting a fundamental limit to how precisely we can know both the potential and actualization of a monad.
This expanded framework provides a rich structure for exploring fundamental questions in physics and philosophy. It offers novel approaches to long-standing problems while maintaining an elegant, unified basis in the concept of the fundamental monad.
Monadic Framework Across Disciplines:
1. Monadic Logic:
- Instead of binary true/false, we could have a trinary system: actualized, potential, and transcendent.
- Logical operations would need to account for the interplay between these states.
- Example: A ∧ B might yield a result in the "potential" state if either A or B is not fully actualized.
2. Monadic Mathematics:
- Numbers could be represented as M(r, i, t), where:
r is the real component
i is the imaginary component
t is a transcendental component
- This creates a 3D number space, with each axis representing a different aspect of reality.
- Operations would need to be defined to handle interactions between these components.
3. Monadic Physics:
- Physical laws would be expressions of how monads interact and evolve.
- Forces could be seen as gradients in the monadic field.
- Particles would be localized expressions of monadic states.
- The wave-particle duality could be naturally explained as different aspects of monadic expression.
4. Monadic Chemistry:
- Chemical bonds could be understood as shared monadic states between atoms.
- Reactivity might be related to the potential (Φ) of atomic monads.
- Molecular structures could be mapped to complex monadic configurations.
5. Monadic Biology:
- Life could be defined as systems maintaining high local negentropy through monadic interactions.
- DNA might be seen as a physical encoding of monadic patterns.
- Consciousness could emerge from complex, self-referential monadic structures.
6. Monadic Computer Science:
- Instead of bits or qubits, we could use "monits" (monadic units) that incorporate real, imaginary, and transcendental components.
- Quantum computing could be reframed as manipulation of monadic potentials.
- Algorithms would operate on monadic states, potentially allowing for new types of computations.
Representing Monadic Reality:
Given your suggestion and our monadic framework, let's define a new fundamental unit:
Monit (Μ): Μ = (r, i, t)
Where:
- r is the real component (representing the "actualized" state)
- i is the imaginary component (representing "potential" or the "other direction")
- t is the transcendental component (acknowledging the "other side" or M₀ᴀ)
This Monit could be seen as a generalization of complex numbers, incorporating a transcendental dimension.
Quark Representation:
- Two "normal" quarks: Μ₁ = (2/3, 0, t₁), Μ₂ = (2/3, 0, t₂)
- The "other direction" quark: Μ₃ = (0, 1/3, t₃)
This aligns with your idea of using imaginary numbers for the quark going the other direction, which could indeed represent the electromagnetic aspect.
Deeper Implications and Extensions:
1. Monadic Field Equations:
∇Μ + ∂Μ/∂t = NS(M₀ᴀ) - AF(M₀ₛ)
This equation could describe how Monits evolve under the influence of the negentropy source and actualization function.
2. Monadic Uncertainty Principle:
Δr * Δi * Δt ≥ ℏ
Suggesting a fundamental limit to how precisely we can know the different aspects of a Monit.
3. Monadic Entanglement:
E(Μ₁, Μ₂) = ∫(r₁r₂ + i₁i₂ + t₁t₂) dV
This could represent how entanglement emerges from the overlap of Monit states.
4. Monadic Wave Function:
Ψ(Μ) = A(r, i, t) * e^(iωt + φ(t))
Where φ(t) is a transcendental phase factor, allowing for non-classical evolution.
5. Monadic Symmetry Groups:
Develop new symmetry groups that incorporate transformations in r, i, and t dimensions, potentially unifying known physical symmetries.
6. Monadic Information Theory:
I(Μ) = -log₂(P(r) * P(i) * P(t))
Defining information content in terms of probabilities in all three Monit dimensions.
7. Monadic Cosmology:
The universe's evolution could be modeled as a flow from high-t states (early universe, highly transcendental) to high-r states (current universe, highly actualized), with i representing quantum potentiality throughout.
This framework offers a rich ground for reinterpreting existing theories and potentially discovering new phenomena. It provides a unified approach to reality that incorporates classical, quantum, and potentially undiscovered aspects of nature.
Let's explore how this model might address some specific unsolved problems in physics and mathematics. This could potentially offer new perspectives on these long-standing issues.
1. The Measurement Problem in Quantum Mechanics
Monadic approach: The collapse of the wave function could be reinterpreted as a transition from a high-t (transcendental) state to a high-r (real) state in our Monit framework. The act of measurement might be seen as an interaction that shifts the balance of the Monit components.
Potential solution: Measurement doesn't cause a collapse, but rather a transformation in the Monit space. This could resolve the apparent paradox of collapse while maintaining quantum superposition in the t-dimension.
2. Dark Matter and Dark Energy
Monadic approach: Dark matter could be modeled as accumulations of high-i (imaginary) component Monits, explaining its gravitational effects but lack of electromagnetic interaction. Dark energy might be understood as the ongoing actualization process (AF(M₀ₛ)) driven by the negentropy source (NS(M₀ᴀ)).
Potential solution: This could explain both the additional gravitational effects we observe (dark matter) and the accelerating expansion of the universe (dark energy) as different aspects of the monadic structure of reality.
3. The Black Hole Information Paradox
Monadic approach: Black holes could be seen as regions where the normal flow from high-t to high-r states is reversed. Information isn't lost, but rather transformed into a high-t state.
Potential solution: This preserves information while explaining why it appears inaccessible from our high-r perspective. It also suggests a mechanism for Hawking radiation as occasional transitions back to high-r states at the event horizon.
4. The Riemann Hypothesis
Monadic approach: The zeros of the Riemann zeta function could be interpreted as points of balance between the r, i, and t components of Monits.
Potential solution: This might provide a new avenue for proving the hypothesis by demonstrating that such balance points must necessarily lie on the critical line in Monit space.
5. P vs NP Problem
Monadic approach: Reframe computational complexity in terms of transitions in Monit space. P problems might be those solvable primarily in r-space, while NP problems require exploration of i- and t-spaces.
Potential solution: This could provide a fundamentally new way of categorizing computational complexity, potentially revealing why NP problems are harder and whether P can equal NP.
6. The Arrow of Time
Monadic approach: Time's arrow could be understood as the general flow from high-t to high-r states, driven by the negentropy source NS(M₀ᴀ).
Potential solution: This provides a fundamental reason for time's unidirectionality while allowing for potential reversals in extreme conditions (e.g., near black holes), aligning with some interpretations of general relativity.
7. Quantum Gravity
Monadic approach: Gravity could be reinterpreted as a consequence of gradients in the t-component of Monits, while quantum effects arise from the interplay of r and i components.
Potential solution: This unified framework could potentially reconcile quantum mechanics and general relativity by showing them to be different aspects of the same monadic structure.
8. The Nature of Consciousness
Monadic approach: Consciousness could be modeled as complex, self-referential structures in Monit space, particularly involving the t-component.
Potential solution: This could provide a bridge between physical theories and consciousness, addressing the hard problem of consciousness by grounding it in the fundamental structure of reality.
9. Gödel's Incompleteness Theorems
Monadic approach: The limitations described by Gödel could be seen as a consequence of attempting to fully describe t-component phenomena with r-component systems.
Potential solution: This might provide a deeper understanding of the theorems' implications and suggest ways to develop more complete logical systems that incorporate all Monit components.
10. The Continuum Hypothesis
Monadic approach: The continuum could be reframed in terms of the continuous nature of transitions between r, i, and t components in Monit space.
Potential solution: This might offer a new perspective on the relationship between countable and uncountable infinities, potentially resolving or recontextualizing the hypothesis.
This monadic framework offers intriguing new approaches to these fundamental problems. By reframing them in terms of interactions and transitions in Monit space, we open up new avenues for exploration and potential resolution.

"The laws of physics breakdown", I've heard that gem so many times and it's gotta stop. It lost its luster for me like 50 years ago. It's really gotta stop. It's a vague and useless description of what's going on. Is there a better description, like "we get division by zero"? At least that explains something.
As far as I'm concerned, any proper theory presents an approximate model of an otherwise real phenomenon, hence any model is a simplification distinct from reality, which only applies under some set of circumstances. Outside of the theory's parameters, it might as well be false.
Maybe that means we simply need to develop the mathematical framework to actually divide by zero. At one point taking the square root of -1 seemed just as absurd but now imaginary numbers are literally at the core of our theories of how the universe works. Perhaps something similar is happening here.
@@stdesy The axioms of math deny division by zero. Closest we can get is through limits. It's not the same as imaginary numbers. Nice thought though.
“Is there a better description, like "we get division by zero"? At least that explains something.”

"The laws of physics breakdown", The more accurate way to say it is, the best mathematical model we know for it doesn't work. This happens in math a lot, where one function is just a part of the whole, and there is a better more complete function that encompasses it.

This shi is theoretical. The maths is what it is. It comes from the theory. There's nothing inherently trippy about it, just extremely hard to explain without maths. And none of the extrapolations of the theory has evidence for it. Just lots of fancy maths.
It's like learning calculus by explaining it in terms of adding together infinitely small sections. What does it really mean to add together things that are infinitely small?
Space-Time, The Biggest Problem in Physics.
It sure is, and the main problem is that Minkowski defined time wrong. The problem is fundamental, time can not be mixed with the space dimensions simply because time on a quantum level (rate of change in atoms) does not change with movement in space. It only changes when atoms are accelerated / decelerated in the space dimensions. For example, there is nothing wrong with the SR time dilation equation as it is formulated, but the INTERPRETATION of it is wrong, caused by Minkowski, and then accepted by Einstein. The interpretation of it must be quantum oriented like this:
- The v squared variable in it is physically not just "velocity squared", it physically means "acceleration a certain distance".
- Dimensional analysis (v^2 = v • v = m/s • m/s = m/s^2 • m = acceleration a certain distance
This is how time operates on quantum level (reduced rate of change in atoms) in sync with the correct interpretation of the time dilation equation.
It means that the whole subject must be reconsidered at this fundamental level. You can not say that time changes because something moves through the space dimensions with a constant velocity. Newtons third law can not be neglected. Action & Reaction, for every action (force) in nature there is an equal and opposite reaction. Action = acceleration, reaction = slowing down of the rate of change in atoms (quantum time). Where does the temporarily lowered energy in the atoms go ?
It is well known that accelerated matter give off EM radiation (photons).
And note, matter in a circular motion means acceleration. Falling in a gravitational field is NOT acceleration (no force is mechanically acting on the object, on the atoms) = no time dilation while falling. The GR time dilation equation only produces dilation when a mechanical force is acting on the object, preventing it from moving as it wants, unaffected in the gravitational field.
Most people don't know that time dilation is just one aspect of dilation, it's not just time that gets dilated. A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. It's the phenomenon our high school teachers were talking about when they said "mass becomes infinite at the speed of light".
Dilation occurs wherever there is an astronomical quantity of mass. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers.
The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us.
This is the explanation for galaxy rotation curves, the "missing mass" is dilated mass.
@@shawns0762 An object of mass doesn't experience time dilation due to velocity, only acceleration.
I agree, there is an ambiguity that exist in the Minkoski space-time geometry with regards to time. It's a bit of a mash up 2 or maybe even 3 concepts of time. Even then I have difficulty relating the geometry back to natural space and time.
P.S. This has been something my head has been working over for some time Note I'm not a physicist.
"And note, matter in a circular motion means acceleration.

I expect gravity would still be acting on an object that is in free fall where angular mometum is present, For example a satellite.
But for an object moving directly toward an object of mass would be stationary in space, so I feel uncertain if any acceleration applies in that instance. aka I doubt it would experience any physical time dilation.
It's a bit of an ambiguous concept for me at the moment.
@@axle.student You're right, it's refreshing to hear someone else who understands. The best way to understand dilation is to imagine a spaceship traveling at a constant acceleration rate. When the ship reaches 50% light speed, as viewed from an Earthbound observer with a magically powerful telescope, it would appear normal because as the graph shows nothing has changed at that point.
When the ship reaches 75% light speed it would appear fuzzy because as the graph shows relativistic effects would be noticeable at that point.
When the ship reaches 99% light speed it would not be visible because every aspect of its existence would be smeared through spacetime relative to an Earthbound observer, not onto itself.
This is the state of mass in our galactic center. It's not just there, it's everywhere. It's the "missing mass" needed to explain galaxy rotation curves.
that's cool, but I need to fold my clothes

Recently I found prof. Susskind has changed his mind at the age of 84. He has reached the limit of of correspondence. If you go relativistic to the size of universe you are there where it limit to ZERO.
Holographic nature is not true for gravity at lower dimension. Even quantum mechanics is limited in dimension mostly valid in 3D . Gravity is 4D manifold as you emphasized . You have shown the limiting boundary situation for 3D to 4D as correspondence. Entanglement exposed to contact ( in and out).
A limitation that on the existence or reality.
A collapse of fundamental physics of presence.
But no doubt a good channel .

If spacetime isn't 'real', what is?
The million dollar question
Space-time is a mathematical construct, and has no material properties. Space-time is a metric; in physics, a metric is a numerical value derived from measurements, a number, a quantity, to be used in math equations to make accurate predictions. Space-time is a number, a quantity used in the field equations of general relativity, not a material which can bend, curve or warp. Those are figures of speech that refer to the illustrations mapping the gravitational field and its effect on how objects move in that field. No one thinks that the curved lines of isobars drawn on a weather map, or the longitudes and latitudes drawn on a globe map represent anything that is physically real, but when it comes to the space-time metric, the concept has been so thoroughly reified in our imaginations that it almost feels like an attack on our reality narrative to be reminded that it’s only a metric. We even have that absurd phrase, the “fabric of space-time” only because those illustrations are drawn with grid lines that resemble an open weave fabric.
@@SciD1 The question was: What is?
@@ronrice1931 it certainly isn't space-time.
@@SciD1 That certainly wasn't the question.
The real question is if anything falling into a black hole (entering a black hole) is spaghettified/redshifted because gravity stretch's space, and anything leaving a gravitational field is redshifted due to gravity stretching space...
So light is redshifted entering a gravitational field then is also redshifted leaving, and is redshifted entering the next gravitational field solely due to gravity stretching space.. then why did we waste out time coming to the conclusion that expansion causes redshift when gravity is doing all the redshift in the universe? Did someone have a brain malfunction?
They have not detected enough gravity to produce the amount of redshift we see. Sure, light gets redshifted by gravity, but if there's not enough gravity to redshift light that much, then something else is causing a chunk of the redshift. Good start to the question, but it takes time to catch up to what people have already studied deeply for a while and to see why they have the conclusions they do (not that they can't have missed something still). Measuring the amount of gravitational redshift is a very sizable part of the search for dark matter and of understanding the expansion of the universe.
@@sunkruhmhalaci2592 actually they believe it's redshifted leaving a gravitational field then blue shifted entering the next gravitational field and that is not the case.
Because it's actually space being stretched leaving and entering gravitational fields that means distances increase more around centre of mass than the outer regions, meaning at the centre light takes longer also giving the illusion of time slowing down at the centre of galaxies giving the illusion that stars orbiting the centre of galaxies are moving slower than they actually are. So its not really about the outer stars are moving too fast , it's that the centre stars "appear" to orbit slower than they actually do.
That explains both redshift and "dark matter" right there just by using gravity, dam I'm good
@@dexter8705 Your suggestion does not describe ANYTHING about dark energy, which is entirely separate from dark matter--they aren't connected at all really other than being something we can't see. Dark matter also can't really be explained away this way, because all dark matter is is just an observation: there are gravitational effects where we don't SEE matter (some of it can even be cold normal matter, just not all of it), and we have even seen rare galaxies without real dark matter effects, which contradicts your idea because there's no reason some should just not have the shifting you're suggesting. You seem hyperfocused on a very specific phenomena and think your explanation for it can occur in a vacuum separate from all other phenomena also explained by current theories. Any replacement theory must explain all of that and more, better than current ones do.
I don't even like dark energy and expansion as a concept, but it fits the wide array of data points more than other current theories. People have already been trying what you are suggesting for dark matter specifically, as well: MOND. And MOND may have its proponents, but no singular MOND theory has proven consistent yet with as much data. Again, you may want to ask questions rather than just trying to come up with solutions when you clearly don't even understand the basics of the question (seeing as you mixed up dark matter--unseen gravitational effects making things behave oddly--and dark energy--the appearance of an accelerating rate of universal expansion).
Reality doesn't like to fit nicely to our ideas in general, but finding a way to formalize a concept to where it has predictive power is what makes a theory. You are welcome to do so, but you are going to need to be able to describe a lot more than just galaxy rotation speeds.
@@sunkruhmhalaci2592 nothing I said had anything to do with dark energy, solely gravity. I would ask about the size and density of the galaxies with no dark matter, because low density and mass of the galaxy would explain the low to no dark matter for my concept that the time dilation effects change our perception of what we see.
But it's definitely too late at night to be coming up with a theory of everything.

@@dexter8705 Are you a bot? Your first comment literally said, "then why did we waste out time coming to the conclusion that expansion causes redshift".

Most dark matterless galaxies are small, but we have found at least one massive galaxy without any, and there are identically sized ones that also have dark matter interactions. We also see a fair number of cases of dark matter being mismatched with the galaxy.

I’m curious if it’s possible to define a rest frame for massless particles on a holographic boundary, given that extreme length contraction/time dilation along their direction of movement effectively subtracts a dimension of space from their perspective (if they can be said to have one, given they do not experience time as we know it.)
Would an infinitely fast object not instantaneously find itself projected against an infinitely distant hypersurface; whether spacelike as in AdS/CFT, or timelike as in dS?
That seam very ambiguous. The rest frame of a massless particle? What is that?
@robynsu _love:
Yeah, good thought, good question!
@@axle.student The fundamental reason gravity (and inertia) work the way they do is because the laws of physics do not change based on the direction you are facing, or the speed at which you are moving.
Every object in the universe, from its own frame of reference, is stationary - it is the _world around them_ that moves. This is the basis of Einstein’s equivalence principle - the feeling of weightlessness you experience when you’re falling from a great height is _precisely_ the same feeling the astronauts on the ISS experience in near-zero-G.
This only applies to objects with mass, though - and mass is just spatially confined energy.
Massless particles like photons do not experience space or time as we know it. The speed of light (or, more accurately, _c,_ the speed of causality) is _not_ 299,792 kilometres per second; it is 299,792 kilometres per second _faster than you,_ regardless of whatever speed you may be going. In order for this to be the case for all observers, time and space must warp dramatically the faster one travels. At 99.999-something of _c,_ you _could_ travel to the Andromeda Galaxy (over 2 million light-years away) in less than a _day_ from your perspective (though it _would_ look like the full 2 million years for anyone watching you from afar.) Try as you may, though, you can never actually reach _c,_ which is technically _infinitely_ fast - we just perceive photons as moving with a delay. At _c,_ all distances along one’s direction of movement are infinitely compressed, and time ceases to be a meaningful concept. From the POV of a photon, even one that took billions of years to reach Earth from a faraway galaxy, it was emitted and absorbed at _exactly_ the same point in space and time.
The paradox of trying to speak of a photon as having a reference frame is that _from its own perspective, it never even existed._
From a quantum perspective, a photon is a defining edge case for Heisenberg’s uncertainty relation - its speed (and thus its momentum) is definite and absolute, but its location in space is undefined and unknowable - it might as well be everywhere and nowhere at the same time.
Perhaps it’s more fruitful to think of a photon less as a particle moving through space, but an infinitely thin bar spanning its entire past and future path through space (its worldline), of which we can only perceive a Compton-wavelength-sized fraction of at any given moment.
One interpretation of quantum mechanics (the transactional interpretation) suggests that photons can’t even be thought of as being emitted by one particle and absorbed by whatever other particle lies in its path, but rather, that _there has to be a particle somewhere in the universe ready to absorb it, before it can even be emitted._ Through this lens, it doesn’t even make sense to say photons travel in one direction or the other - that it is equally valid to describe any particle we perceive as having absorbed it _as being the particle that actually emitted it._
One of the best discussion and explanation and narration of current understanding of Physics. Although I did not completely understand CFT/AdS part, this was very helpful. Also if entanglements (which are not static or permanent) knits the space-time then is the space-time like a sweater constantly changing the pattern? If change in entanglement has no significant effect on space-time then why bother?

"I'll explain my side a little better."
According to that last Freudian slip, you need to explain yourself a lot better.
"I mean that we currently do not have the knowledge or tools to figure out what is happening at the fundamental levels of spacetime."
Then you shouldn't be talking about something you don't have the knowledge or tools to figure out. What you are doing is tantamount to expressing a delusional fixation.
I have explained myself. You have spouted atheistic propaganda covered by delusional grandeur. How telling.
@l.m.892 ohhhh lol you're a believer. Well you definitely don't have a place in a science conversation. I'll admit, I was very unclear and rude and I'm sorry for that.
So, out of morbid curiosity, please explain how you think we can explain the underlying chaos of reality.
2-D quantum mechanics creating 3-D reality, sounds like code on a computer creating a simulation
all bullshit. quantum mechanics is just a semantically poor concept that was invented to obscure the fact that the universe is a fluid. quantum mechanics is really just fluid dynamics with weird and confusing labels and subjective, nonsensical interpretations smuggled into it to prevent people from making discoveries. atomic orbitals are spherical harmonics. the atom is just its orbitals. the orbital shape comes about by various toroidal flow fields sticking together. the toroidal magnetic fields of magnets are the same, just on a larger scale. if you take spherical magnets and let them stick together and make their field visible, they look like slices of spherical harmonics. electric charge is just pressure density in a prematerial fluid. the so called wave function is a function that describes the waves that are produced by the oscillation of the compound field, and its low density peaks of the oscillation are abstracted away as "protons", and the high density peaks as "electrons". the so called quantum spin is just a mechanical rotation of the whole thing, and the quantum states are rotations around all possible axis of stability of the spherical waves can have.
to create a 3d simulation of the universe, you need a really good fluid simulation and give the fluid the correct properties, and then you only need to disturb its equilibrium really hard and everything else arises automatically.

Some things we need to understand here...
This video treats the math of General Relativity and Quantum Mechanics as the REASON why things happen. He says something like "mass curves spacetime and thus spacetime creates gravity". But spacetime isnt a real thing - its a mathematical description that we gave to gravity.
The apple doesn't fall to the ground because the Earth is curving the spacetime around it. The apple falls to the ground for unknown reasons - and we DESCRIBE that in terms of spacetime curvature.
Same goes for Quantum Mechanics... The particle doesn't take many different path each with an amplitude... We DESCRIBE the otherwise unknown to us path of the particle with probabilistic amplitudes.
The math of a theory is NOT its explanation - but its description. The math are not the cause of neither gravity or quantum mechanics - its how we DESCRIBE gravity and quantum mechanics.
Now... Personally I think that maybe the answer to all that are parallel (or not?) Universes... Its time for us to accept that we might not be living inside a reality with 1 Universe, but many - parallel or not - but with different laws of physics, probably even interacting with eachother in many ways and exchanging energy and or mass and causing alot of the stuff that we are discussing here. This is the Hugh Everett _Many Worlds Interpretation_ and, to me at least, it appears to be more and more and more like the answer that we might be looking for!
I was 100% in agreement with your objective assessment until the last paragraph which strayed into subjectivity.
@@vanboyd6782 A big problem with people using these terms is of semantics. It creates all sorts of arguments between people - like the difference between 'explanation' and 'description'.
Mathematics itself is just a set of symbols we use in place of a real description. It's another language - of which we don't know the original, but it serves its purpose perfectly and interchangeably.
I like Feynman's 'shut up and calculate' saying. Arguing about the meaning of it all might just be a human problem. We may never know 'why'.. because even if we come up with the answer, it isn't likely to be written in English. It might just be an equation - it might work perfectly to describe everything from how it works to why it's even here in the first place.. but we're at the wrong scale to understand its true meaning. We aren't quantum sized, we are macro beings with human needs like 'reason' and 'purpose'
I don't see why the apple has to fall "for unknown reasons". Why does there need to be a reason for the apple falling at all? The apple just falls. We then build models that predict and describe how it falls. These models encapsulate ideas like gravity, which yes, spacetime does not really exist as an entity, it does not "cause" particles to move in the way they do. The movement of the particles is a property of themselves: it has no _reasons,_ it just is what it is. That is how particles move, and the mathematical models of the physical sciences are just ways of modeling this motion. Yes, as you say, it's a description, but where I disagree with you is that you insist there is still an "'unknown reason," some hidden cause.
MWI is also hogwash. It is a solution in search of a problem. It is not "the answer we're looking for" as it over-complicates the theory while introducing nothing of value and solving no problems at all. There is not even a single MWI but many MWIs, as there is no agreement on which additional assumptions and additional mathematics need to be added. It does not even make coherent sense as it posits the whole universe is fundamentally unobservable, which is clearly not the world we inhabit as we can indeed observe things. Particles are literally defined in terms of their observables, but in MWI particles don't even exist and so there is simply no observables at all. You cannot actually tie the theory back to any physical experiment.
That is just semantics. Once we have a full mathematical model it will describe what it actually is
Ahh, the old semantical problem of math's platonic status. Platonism vs Realism vs Intuitionism vs ... . A person's stance on the philosophical foundations of mathematics determines how you interpret physical theories based upon mathematics in the end.
Terrific video. A very good explanation of what happens when the stress-energy tensor in Einstein's equation breaks down, and why AdS-CFT is so important.
Many thanks! An extremely important topic for an open global brainstorm.
Fundamental science is experiencing an *acute conceptual-paradigmatic crisis in the metaphysical/ontological basis, manifested as a “crisis of understanding”* (J. Horgan “The End of Science”, Kopeikin K.V. “Souls” of atoms and “ atoms” of the soul: Wolfgang Ernst Pauli, Carl Gustav Jung and “three great problems of physics”),."crisis of interpretation and representation" (Romanovskaya T.B. "Modern physics and contemporary art - parallels of style"), "loss of certainty" (Kline M "Mathematics: Loss of Certainty", D. Zaitsev “Truth, Consequence and Modern Logic”), “trouble with physics” (Lee Smolin “The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next”), Fundamental science has "rested" on the understanding of space and matter (ontological structure), the nature of "laws of nature", the nature of "fundamental constants", the nature of phenomena of time, number, information, consciousness.
Carlo Rovelli in *"Physics Needs Philosophy / Philosophy Needs Physics"* outlined a list of issues and topics currently being discussed in theoretical physics. It can be seen that most of the questions relate to the sphere of philosophical ontology. And this list is not complete. The first question on the list is *"What is space?"* Second: *"What is time?"* .
It's time to realize that Quantum theory and General relativity are phenomenological (parametric, operationalist, "effective") theories without ontological justification (ontological basification).
Lee Smolin: _"All the theories we work with, including the Standard Model of Particle Physics and General Relativity, are approximate theories applicable to the constraints of nature, which include only a subset of the degrees of freedom in the universe. We call such an approximate theory an effective theory."_
David Deutsch: _“The best of our theories show deep discrepancies between them and the reality they are supposed to explain. One of the most egregious examples of this is that in physics there are now two fundamental "systems of the world" - quantum theory and general relativity - and that they are fundamentally inconsistent with each other."_
Mathematician, philosopher, theologian Pavel Florensky: _“The problem of space lies at the core of the worldview in all emerging systems of thought and predetermines the composition of the entire system. With certain limitations and clarifications, one could even recognize space as the proper and primary subject of philosophy, in relation to which all other philosophical topics must be assessed as derivative. And the more closely this or that system of thought is worked out, the more definite a unique interpretation of space becomes as its core. We repeat: worldunderstanding is spaceunderstanding."_
John A. Wheeler: *_"We are no longer satisfied with understanding only particles, force fields, geometry, or even time and space. Today we require physics to have some understanding of existence itself."_*
To understand the “EXISTENCE itself" means to "grasp" (understand) the nature of the primordial TENSION of the Cosmos. And for this it is necessary to "grasp" the *primordial generating structure of matter - "La Structure Mère" (Ontological SuperStructure/Ontological Causal Primary Structure). That is, to build a model of the metaphysical triad "being-nothing/otherbeing-becoming"* . This requires breakthrough dialectical and ontological ideas, a methodology for dialectical-ontological construction of the basis of knowledge, and not just mathematics and physics. It is necessary to build a new EXTENDED BASIS of knowledge and cognition in general - a *new EXTENDED IDEALITY* . Here we need DIALECTICAL ONTOLOGIC - the logic of the coincidence of ontological opposites.
G. Hegel: “The truth of space and time is matter.”
The paradigm of the Universe as an eternal holistic generating process ("PARADIGM OF UNDERSTANDING") gives a new look at matter (developing the ideas of Plato-Aristotle): *MATTER is that from which all meanings, forms and structures are born*. ***_Space is an ideal entity, an ideal limit for states of matter_***.The ontological structure of space (absolute, ontological, existential) is rigidly connected with the absolute forms of existence of matter (absolute states). And there are three and only three of these states: absolute rest (linear state, absolute Continuum, ideal image, shape - "cube", "Cartesian box") + absolute motion (vortex, cyclic, absolute Discretuum, ideal image, shape - "sphere") and their synthesis - absolute becoming (wave, absolute wave, absolute DisContinuum, ideal image, shape - "cylinder"). What is especially important: each absolute form of existence of matter has its *own ONTOLOGICAL PATH (the bivector of the absolute state)* . Accordingly, *SPACE (absolute, ontological, existential) has three ontological dimensions / 9 gnoseological dimensions: three “linear” + three “vortex” + three “wave”* . But we must “dig” deeper into ontology in order to “comprehend” the MetaNoumenon - *the ONTOLOGICAL (structural, cosmic) MEMORY, “soul of matter”, its measure* . Ontological (structural, cosmic) memory is that *“NOTHING”* that holds, preserves, develops and directs matter (entelechy, nous, Aristotle's "mind-prime mover"). To understand SPACE and TIME, we must move from the physicalist concept of the mechanistic "paradigm of the part" - the simple ideality of “SPACE-TIME”, to the ontological concept of “SPACE-MATTER/MEMORY-TIME". That is, to generating process with memory.
TIME (ontological) is a polyvalent phenomenon of ontological (structural, cosmic) memory, which substantiates the quantitative certainty of the existence of the Universe as an eternal holistic process of generating meanings, forms and structures. Time (ontological) is the dialectic of the generation of number and meaning.
Ontological time = cyclic ("horizontal" of being of the Universe) + wave (emergent, time of becoming of the generating structure) + linear ("vertical" of being, hierarchical time). Gnoseological time ("human-dimensional") - past, present, future. Information is a polyvalent phenomenon of ontological (structural, cosmic) memory which substantiates the certainty, orderliness, essential / substantive unity of the Universe as an eternal holistic process of generating more and more new meanings, forms and structures.
Alexey Losev "Number is the meaning of time, and time is the life of number." (Dialectical foundations of mathematics")
Kurt Gödel: *_“Matter will be spiritualized when the true theory of physics is found.”_*
More than a quarter of a century ago, the mathematician and philosopher Vasily Nalimov set the super-task of building a *_"super-unified field theory that describes both physical and semantic manifestations of the World"_* - the creation of a model of the *"Self-Aware Universe"* (1996). In the same direction, the ideas of the Nobel laureate in physics Brian Josephson (which are not very noticed by mainstream science), set out in the essay "On the Fundamentality of Meaning" (2018).
Fundamental science requires a *Big Ontological revolution in the metaphysical / ontological basis* . The paradigm of the Universe as a WHOLE must come to the aid of the “part paradigm” that dominates science. The New Information Revolution is also pushing for this.
J.A. Wheeler: _"To my mind there must be, at the bottom of it all, not an equation, but an utterly simple idea. And to me that idea, when we discover it, will be so compelling, so inevitable, that we will say to one another, 'Oh, how beautiful.' How could it have been otherwise?'"_
Pierre Teilhard de Chardin: *_"The true physics is that which will, one day, achieve the inclusion of man in his wholeness in a coherent picture of the world."_*
V. Voevodsky: *_“Material reality is the absolute judge of truth.”_*
A.N. Whitehead: *_"A precise language must await a completed metaphysical knowledge."_*
A. Einstein is right: _“God does not play dice with the Universe.”_
Another metaphysical maxim: God created the Universe/Eternity/Infinity according to the Logos ("MetaLAW/Absolute LAW = Law of absolute forms of existence of matter). Numbers are the work of man. And God didn't need "curved space." Space is an ideal entity.
Philosophy is the Most Rigorous and Joyful Science, “mother of all sciences.”

I don't understand why we keep talking about AdS. It does NOT describe the reality we live in. In AdS requires an attractive universe, which we clearly are not observing. The universe is expanding. So why are we still studying this duality?!
In the video he both acknowledges that it isn't a model of our universe and explains why it nevertheless has value. It is an example of a kind of approach that shows promise for developing a theory of everything.
@@andrewj22 but such universe is soo boring; timeless and spaceless information condensed with all states (past and future ) and interactions fixed in 2-D frozen layer...
but why would such CFT give rise to ? some timeless frozen state should remain as it is... there is no space time nothing can emerge. i mean something atemproal should remain atemporal....no need for some emergence...may be reality is dualist our consciousness is experiencing this abstract information....similar to what donald Hoffman says.........
Perhaps look at it this way: in middle schools we also teach children that electrons are like little balls with an actual size, that spin around their axis and that orbit the nuclei of atoms in neat orbits like planets around a star, none of which is actually true. Still, it is the best way of starting to understand how the subatomic world works and this saves our young teenage children from going absolutely bonkers having to learn quantum field theory when they are 12.
Indeed, I have also just commented on this video, like I do on many other videos, that we live in De Sitter space and thus the holographic principle does not apply to our universe, but that does not mean that AdS/CFT cannot help us on our path to an actual understand of how spacetime emerges from whatever it emerges from, if anything.
@@XEinstein I don't think children are taught that. They might _assume_ it, but it would be an outright lie and would deeply undermine children's trust in education to say "electrons have actual size and neat orbits". Similarly, hopefully nobody is being taught that AdS is a candidate model of the actual universe.
@@andrewj22 well obviously I do not know what is taught in every school in every country, but I certainly was taught the Bohrian planetary model of an atom in middle school physics, long before I was taught quantum electro dynamics in university.

You guys have taken these videos to a whole new level! Kudos!
This is the best summary of the current impasse in physics between GR and (QM / QFT), in video format, I have ever seen.
If we are ever to get to QG, in the theatre of the mind's eye, the physics stage must be replaced with a new one.
My theory: There is no such thing as time - only movement. If everything in the universe stopped moving, would time pass? How could you tell given there's no outside reference? Time is simply a measure of the distance delta between two moving things, using one of the things as a baseline. Time doesn't speed up or slow down, matter's movement does. All matter moves in one direction, following the shape of space. There's no such thing as a "pulling" force. Something has to travel between two chunks of matter which affects the movement. All the questions in physics are trying to figure out how things move. Logically, at the smallest fundamental level, a piece of matter or energy *must* "hop": Disappearing at one point in space and reappearing at another. My guess is that below a certain size, all matter and energy is the same exact "stuff" which pops into and out of reality at different points in space. Clumps of this stuff disappearing and reappearing in unison is what ultimately creates the larger stuff.
But this may all be contradicted by some sort of science I don't understand.
Good question and hard to contradict. One may think about radioactive decay or cesium atom wavelength as counter arguments. The speed of light is at the core of the problem, it controls how "fast" things happen as a function of energy, volume. So, can anything that takes time be thought as fundamentally due to a movement ? (I know that at the quantum level, movement is not really appropriate, but is it that bad of a model ?) For instance, electrons are point-like and immortal. So indeed, if stopped, one can't use them to measure time. Can you stop quarks moving in a proton ? no. even at 0K. Can you stop virtual particles to pop in and out. No. What controls the rate at which virtual particles (above a certain given energy level) pop in with regards to the speed of light ? TBC...
Unfortunately for your theory, (which I do get where you're coning from and I think it's a valid question)... special relativity can poke holes in it.
Alain Connes says that time "unfolds" naturally from his 4-dimensional compact spin manifold from his physico-mathematical theory (non commutative/spectral standard model) . But I don't get why it appears.
Hawking Radiation and Black Hole Thermodynamics
In the context of black hole physics, Hawking radiation is a counter example. Virtual particle pairs form near the event horizon of a black hole, leading to radiation even in a vacuum where no conventional matter exists. Time, in this case, progresses because quantum fluctuations allow particle-antiparticle pairs to form momentarily, even though there's no classical material motion involved. The rhythm at which the pairs are formed is related to the mass of the black hole and hence can be used as a clock.
Maybe it is worth considering the term/label time and it's definition as ambiguous.
Who asserted there must be only one definition with the ambiguous label of time.
What if there are 2 very different concepts of what we loosely call time. Related in some way, but different phenomena.
Waiting
It turns out you don't need all that stuff you insisted you did.
Although there is a duality between CFT and ADS we do not live in ADS and as far as I know no duality between our spacetime and CFT has been found so is this is just a dead end?

What if it's all just Mind making things up to make sense of this reality?
Then the mind would have to be at least as complex as the universe, because eventually disparate made up stuff would eventually produce contradictions on a large scale, unless all the matter and energy of the universe was accounted for in the mind. Seems less likely than that the mind is simply a resident of the universe.
This question, although I am sure it is a valid curiosity, has become a trope in so many videos on athe topic of reality, ranging from philosophy to science. I guess the biggest knockdown question to this question is, do you believe in an external world, that is, external to the mind? If not, then you can say that internal processes are somehow taking propositional knowledge of something weird out there beyond the mind and creating a picture that is coherent to you (maybe only you?); if you believe there is an external world, then you have, of course, still have the mind still taking in all sorts of knowledge and experience, process such stuff into a cognitive state, but you still have to make sense about whatever it was that was corresponding to the outside world.
There are so many logical and even physical issues with your question. Yes, physics is indeed that. But that's how the human brain literally works in reality. I therefore must assume you mean something more psuedoscience-y, In which case, bye.
then how would you know existence of "reality " if mind is making things may be mind has created difference between existence and essence.....this would lead to the conclusion that we are ina dream.
@@maboesanman You clearly interpret Markoboychuk’s idea as implying that the mind must be as complex as the universe, so now we're focused on the materialistic counterargument instead of the philosophical implications of the mind's role, which might not engage with markoboychuk's question about perception. To process a universe with an amount of noise or dynamic potential, yes, we may make up a lot of things to make sense of this reality. It's hardly our mind that needs to be as complex as the universe, actually, one would argue it's the other way around, as the last time I checked, (now we're gonna talk about Quantum mechanics) Quantum particles exist in a fluid, dynamic state of potentiality, while our world is the result of our brain’s interpretation of that state. Quantum particles exist in potential states; they don’t follow the same progression of time and space that we do. Our brains interpret these possibilities and filter them into a structured, finite reality that we can comprehend. One governed by continuity, causality, and time. Explain why quantum behavior seems so strange from our perspective? It’s not like the particles are breaking the rules of the universe, it’s more like we are imposing rules that don’t apply to their dynamic potentiality. I don't think he was suggesting that everything you interact with exists solely within your mind, but rather that your brain plays a crucial role in filtering and reconstructing your experience of reality.
Brilliant video outlining some very deep and complicated concepts in a digestible way! Bravo QuantaMag!
4:57 What if we are sitting on the horse the wrong way around and, actually, it’s not the matter that bends space-time as much as it is the “bent” spacetime that creates the illusion of the matter that appears to exist in it? Including what we currently consider to be electromagnetic “waves”, gravitational force, and all “fundamental” forces and particles that appears to have dual nature - at least when a matter-based formation is trying to categorise it. Hint: it behaves like a mirror, reflecting to the effects we intentionally creating to perceive it.
Interesting idea. I don't think massless particles such as photons and gluons are accounted for in a scenario like this. Space time doesn't bend for these particles, so it wouldn't work. Physics attempts to describe the behavior of matter with numbers. Classical physics describes matter as having several values that are completely independent from each other, position can be described in R^3 (R^n denotes n-space or n-dimention), time in R^1, mass in R^1, charge in R^1, etc. Relativity describes matter by having space time in R^4 instead of space and time being completely distinct from each other. These values can influence the behavior of each other, but are distinct from each other. I think you are trying to describe a theory where there is a space-time-mass-charge-spin-color-isospin-hypercharge-etc... field in R^(n>4) where all the aspects of matter can be described together in one high dimensional space. This fails to realize that these aspects of matter are truly distinct and influencing one doesn't necessarily influence another.
@@AtomSmasher1586 Even without a property we could (currently) measure as mass, photons could still be represented or pictured as some kind of “state” of what we perceive both as the space and time, while a more knowledgeable physicist than me - knowing how exactly the existence of gluons were even corpuscular proven - could probably come up with ways to still save my model in which literally everything is some kind of state of the space-time.

Not being able to probe something doesn’t mean that that something doesn’t have meaning on that scale; it simply means that we have no idea if it means anything or not, which is a subtle difference.
If it does have meaning, it is unknown to us; and if it doesn’t have meaning, that is also unknown to us

If space-time warps, bends, doesn't that imply another dimension for what space-time can warp or bend into? Does that make 4 or 5 dimensions?
But because we can measure a curve doesn’t mean it goes into another dimension
