    Just gotta say this: something I really like about Brian Greene is that even though he has opinions on the topic his interview subject is discussing and could easily BE the one being interviewed at any moment, he carefully doesn't interrupted his guests and lets them say what they have to say in their own way. As obvious as it is that doing so is literally the POINT of interviewing guests, almost NO ONE who does it seems to be able to get out of the way. The great Terry Gross of course is the absolute master of interviewing and Brian Greene is just like her in this respect. Thanks Brian.

      2nd, keep it up man. I'm 39 and have been teaching myself physics for over 10 years now. I would suggest that you keep exposing yourself to the highest level content you can sit through, and don't shy away from looking at the math any time it's shown, even if you don't know what it all means at first. I can tell you for a fact that these subjects start to really take shape in your mind over time either way, and it is possible to even get intuitive understandings for aspects of the math over time, with or without the ability to do a calculus problem on paper. But if you ever feel the desire to jump into the math, don't let anything hold you back. Especially grumpy idiots like ^ that guy with a chronic case of backpfeifengesicht, no doubt. (probably also don't start with string theory though, in terms of math, lol)

      Oh yea, and something that helped me a LOT. Whenever you hear a statement that creates a question in your mind, or you don't understand something but you are able to formulate that confusion into the form of a question, ---- write it down! ---- You will be shocked at how often and quickly those questions get answered over time, if you have the wherewithal to jot them down or at least ask them out loud when they pop up. Sometimes I can be struggling with a concept or a line that a physicist says that throws me, for an hour, and then within 60 seconds of writing it down, my brain clicks and says "you already know the answer to this one, you just forgot x y z aspect of it" or "don't you remember so and so was explaining this in that video you saw 3 weeks ago, go find it."
      It's also educational fun to look back at your own questions from 1 year ago, 2 years ago, and you will realize just how much more interesting they have become over time, as you add to your base level knowledge.

      You mean these nonsense and unproven bogus speculations? None of what they are discussing has been proven in a lab. Green is an outspoken atheist, who’s gone on public record stating how he sees no place for God , Christ & the Bible being taught in public classroom. So why should be allow you Brian’s “theories” to be taught as fact? Atheism is being taught as standard religion in the classroom today, where young students are brainwashed into such concepts like “big bang” -A magical explosion which came from nothing, or that all humans are just holographs on a giant TV screen, or how we should spend our time workshopping men like Richard Hawkins, instead of Christ. (Richard Hawkins publicly stated how he wishes for the cross on the Bible to be replaced with a picture of himself… let that sink in for a second…)

      I'm not sure how to interpret your question, so I'll just mention some impressions strengthened by the interview.
      I've come to regard quantum to cosmic phenomena as ubiquitously emergent experience of boundlessly evolving complexity. In other words, probabilistic quarks underlie everything from energetic potential to materialization hosting wildest imaginings. Both his ADS/CFT equivalence and the holographically entangling ER = EPR realization point to this.
      Juan's elucidation of complexifying black holes strikes me as vividly describing ubiquitously emergent quarks, underlying all of perception. Universal emergence is detectable as the forces of nature. Among them gravity, readily observable in macroscopic specificity, attenuates to undetectability at probabilistic quantum scale.
      The holographic imagery inspires a lucid vision of the emergence of the evolving complexity of universal experience.

    I think it is fair to say that the smaller we go, the more complex the Universe is, and this phenomenon is relative across the board. I would suggest that the puzzle is infinitely long. If String Theory is the only mathematically possible explanation, these idea's should be pushed to exhaustion, or until someone develops a radicaly better theory. As it stands the scientific explanations are incomplete, and unsatisfactory, which leaves more space in the human mind to seek for alternatives.There is a balance and a breaking point but we're not there yet, therefore this cannot be deemed as unproductive time spent. Keep up the good work!

    The limit of information within a surface is that of an event horizon for a black hole. the holographic principle would rely on there being a limit of mass that can be within a specified volume before it collapses to a black hole. The curvature limit of space aligns with the information basis of QM.

    Hey Brian. If entropy of a black hole is determined by its surface area and not its volume then it sounds to me that space/time is indeed "flat" (2D). Therefore using entanglement (photon spin), there is nothing stopping us from shooting photon through the event horizon and "reading" what is inside when the corresponding photon (our side) changes after some event inside the event horizon.

    firstly, recent research has shown that Einstein’s theories of relativity hold up when tested against the gravitational pull of the supermassive black hole at the center of our galaxy. this is an exciting development in the field of astrophysics and could lead to new discoveries about the nature of black holes and the universes..
    secondly, the time it takes for humans to accept new ideas can vary widely depending on the idea and the context in which it is presented. some ideas are quickly embraced by society, while others as E.V. take generations to gain widespread acceptance. this is often due to factors such as cultural norms, political climate, and the availability of information. however, it’s important to remember that progress is not always linear, and that even ideas that were once considered radical can eventually become mainstream...

    That was interesting listening, thanks to both of you. A little frustrating in that when I hear talk about the inside of Black Holes, in the thinking that Gravity is a property of the energy interactions within the Higgs Field, gravity cannot exist inside Black Holes to any depth, and so there is no singularity. Gravity ends at the Higgs Field event horizon of a Black Hole at one end and at the Quark energy event horizon at the other. What it also says is that where energy is applied to a particle to accelerate it to near the speed of light, the Kinetic energy accumulated by the particle is visible as “phantom” matter so where this matter can be “created”, at the LHC for instance, a small LIGO module in close proximity to the Proton Beam should be able to detect an increase in Higgs Field energy as a Gravitaional Variation relative to the background Field Energy. Depending on the arrangement I think that the laser should exhibit a red shift as the protons in the beam approach the speed of light. In the so doing this might also demonstrate that Dark Matter might be explained as Phantom Matter, or variations in the Deep Space Gravitation due to variations in Higgs Field Energy Intensity Gradient.

    I find the dimensional reduction argument to be interesting.
    In computer science, everything can be expressed one dimensionally - as an arbitrarily long string of bits, given an appropriately complex interpretive device.
    My thought is if the language we describe the universe in has this property, then perhaps a theory of the universe may also have this property - that dimensionality starts at one, then can be added or removed for interpretive convenience.
    Another interesting property of this computer science language, is that everything is based on logical bits. On the expressive side, this is simply the ability to hang two different symbols on a string, and on the interpretive side, this implies logical differentiability between two meanings.
    In physics, these differentiable meanings don't show up as simple two state binaries, but as complementary pairs. These kinds of precision/accuracy trade offs, and uncertainties, are the hallmark of scientific (rather than purely logical) reasoning.
    I'm not even sure it's possible to have a theory of everything physics, but I think it helps to think about a theory of everything scientific as perhaps the next best thing. We might actually get to the meta theory first.

    • @ywtcc
      @ywtcc 5 місяців тому +1

      So, as an axiomatic starting point, one might propose two experimentally differentiable symbols A, B such that when measured dA*dB>=c, where c is some constant.
      c represents an admission of some amount of unknowability, however small in comparison to the scales of A and B.
      I think this admission of a non zero c in physical logic is essential to engaging in the most precise, comprehensive scientific reasoning.
      I suppose the idea I'm playing with is that Heisenberg's insights have deep metaphysical meaning - it gets to the heart of observability, which is critical to experimental verification, and quantitative differentiability, or the ability to be interpreted.
      In a way, it describes science as a game of chasing a will o' the wisp of unknowability.
      It's the paths described by the chase that are the product of this activity.
      Catching a will o' the wisp was never going to happen, that wasn't the point.
      We knew it was this kind of game when we started, or else it would have been a solved mathematical problem, instead of a scientific problem.

FYI: Quantum Gravity or Quantum Gravitation have three types that are equivalent to and manifested by Quantum Gravitational Entanglement - a Quantum Entanglement at Macroscopic Cosmic Scale namely: 1. Quantum Anti-Gravity = Spin Up Quantum Entanglement State; 2. Quantum Neutral Gravity = Superposition Quantum Entanglement State; and 3. Quantum Gravity = Spin Down Quantum Entanglement State.

    about the area beeing proportional to entropy: it's a bit confusing. Is it always the minimal area (sphere)? how about a space having spikes? then you could have infinite area and infitie entropy.

    The difficulty of combining QM and Gravity is that they combine in the First Cause Causal choice matrix. Energy/mass in spacetime is shape not force. Your problem is the shape of mass/energy in space time is dependent on future choices made. The problem your having understanding the concepts of Relativity and QM and so chasing a sensible matrix of QM with Gravity is your not understanding the only force being applied is in the First Cause Causal choice matrix and QM and Relativity are shape matrix not force matrix.
    You might find matrix formulations to more accurately represent the shapes, but you can't get there abandoning Orientation around First cause causal choice which includes you as a conscious actor as genesis of force.
    The mathematical unification of QM and Relativity is in the testing of Choice as a force of creation. We get this simply by noting the matrix describing first cause choice can be Relative or Newtonian if choice isn't a force of creation. The matrix of physics must be a probability density if choice is a cause. This is tested on both sides with overwhelming evidence.
    QM is a matrix that shows all information at origin, omniscient, omnipresent, omnipotent Origin. Whatever formula's you use this is your limit. Non local/ Local description of action is just poor phrasing.
    You understand QM and Relativity - You don't like that it doesn't mathematically combine so say you don't understand what's causing it.

    Hello everyone. I am a Hp guy from nowhere. First of all thank you to Brian to be an ambassador for the scientific fiend to the latest opinions of the world concerning all matters of the latest theories of the being of everything. Without him we would feel much poorer for the communication of the latest theories of the reality. Although my opinion is that we are overcomplicating the description of the nature of the universe. Obviously Einstein made his mistakes, but his general theory of relativity stands by the method of proof. All these theories remain theories and dreams to me. I understand dreaming is necessary to eventually prove anything new, but this seems like a stretch. String theory does not seem like the answer since the nature has always been proven to be simpler to what we believe it is since Copernicus. Do we have the courage to consider sharper, new creative, simpler new theorems nowadays? I do not think so. Let's at leats consider new solutions to be proven by young, new generation ideas to be proven according to the mathematical method. We have new great technological instruments that can be exploited. Thank you for your consideration & good day to everyone.

    A man and his twin brother say goodbye. The brother goes away to a distant star at a high percentage of the speed of light. The brother then returns. The story was always that the brother who ventured away and came back would age more slowly. However given that everything is relative, how does the universe choose? From each brother’s perspective the other seems to fly away at great speed and then return. Should they both not age at the same rate .?

    Well, in that "holographic" idea, the surface of your hypothetical iso-hypersphere (you hypothesize it being /on/ the edge of the universe, or, at least, very far) is defined as an isosurface, equidistant from your center by the application of the laws /formulas, to be more precise/ of relativistic gravity, so, of course, being an isosurface (hyper or not) it "negates" the gravity, drops it, it's "gravity neutral", because you define it that way, so if you project on it what's inside of it, it will be "gravity-less" by your definition. If you use /formulas of/ relativistic gravity as a projection function on an isosurface, then you /by definition/ end up with a projection of everything but the gravity (and I have a feeling you may not even need to put it as far away as the edge of the universe /which probably does not exist/).
    And please don't get me wrong, as IMHO String Theory is an amazing theory.
    P.S. Actually, if you take my words the other way - if/as you define a zero-gravity isosurface, then, if I am correct, it should prove that your projection on it with relativistic math used as a projection function will eliminate gravity, keeping everything else /in tact/.

    Don't your equations point towards hollow interiors for block holes when it comes to spacetime? The overall schematic picture is space-time gets thinner and thinner as you approach a black hole event horizon, and the entropy depends ONLY on the quantity of the surface for that particular reason. So, the event horizon is equivalent to a geometry defined as a 'surface tension of spacetime blocks'. Then what is gravity? It is an emergent phenomenon of a density gradient change of spacetime building blocks. If all these 'ifs' hold true, then there is no such a thing as 'crossing an event horizon into the interior'. A thing falls into a black hole just to be retained as information at the surface, or if a part of it is to make it through instantaneously on the other side of the EH sphere.

      The fundamental flaw is that they use one dimensional strings.
      If you switch it up so the open and closed strings have a simple cylindrical thickness that is constant with a surface that is very slightly textured such that the bumps and troughs on opposite sides of the cylinder cancel each other out but the location of these bumps and troughs along a length or around a hoop is free to encode information by being an irregular textural perturbation. As a _Theory of Everything_ this provides a unification of _Quantum Field Theory_ and _General Relativity_ without recourse to _Calabi-Yau_ manifolds and getting bogged down in the Swampland of 10⁵⁰⁰ possible solutions, as it is based on a universe with one fewer dimension, thereby limiting the number of solutions, and then one is designated a non-relativisitic quantised time dimension which can be thought of as a tick of a simulation which happens regardless of singularity conditions within the pair of four dimensional universes it governs: one west coast convention [+ - - -] the other east coast convention [- + + +] being the universe we are familiar with. Both have increasing entropy but originate from opposing ends. This T-symmetry, joins S-symmetry and P-symmetry and C-symmetry for a fully symmetric cosmological starting point.
      The math for this is trivial and can be summarised as follows:
      Z⁶⁷¹⁰⁸⁸⁶⁴·⁶⁷¹⁰⁸⁸⁶⁴ U(67108864, 67108864) structure group of Weyl spinors†
      ⇡↓ π₂

      T the 1-dimension of non-relativistic quantised virtual simulation clock time

      P¹·³ our 4-dimensional psuedo-Riemannian spacetime, West Coast [+ - - -]
      !⇣↑ π₁
      O²⁷·²⁷ the 54-dimensional Ehresmannian manifold "behind the scenes"
      ⇣↑ π₂
      N⁶⁷¹⁰⁸⁸⁶⁴·⁶⁷¹⁰⁸⁸⁶⁴ U(67108864, 67108864) structure group of Weyl spinors†
      †decomposed from U(134217728, ℂ) Dirac spinor
      such that U(c, ℂ) where c = 2²⁷ where 27 = ⌊54 / 2⌋
      where H¹·³* x V²⁶·²⁴ → C(Y)²⁷·²⁷ or Spin(1, 3) x Spin(26, 24) → Spin(27, 27)
      You will need to view this diagram in a desktop web browser so that none of the lines undergo word wrap.
      Here, the complexified Spin group with 54 implicit dimensions is based off the cardinality of the unrestricted set of dimensional measures of the 9 dimensions, where P-symmetry can be obtained via a non-chiral theory provided that m = 4k + 2 where k is a Natural number, as a necessary requirement for Complexification:
      Zᵘ·ᶜ U(u, ℂ) where u is the structure group given by the formula U(u, ℂ) where u = 2ⁿ and n = ⌊m / 2⌋

      Yᵐ·ᶜ Spin(m, ℂ) where m is the complexified cardinality of the unrestricted set of dimensional measures of Xᵈ given by m = ⌊(d² + 3d) / 2⌋ ⊗ ℂ

      Xᵈ this d dimensional surface is based on geometry defined by Bernard Reimann where d is a Natural number
      Obviously, this is a larger structure group than we need for observed phenomena, but that just implies that there are more phenomena which have not yet been observed. Given that we infer the existence of Dark Matter yet have not found it experimentally at the LHC or the same in regards to Supersymmetric superpartner 'particles' like the selectron having a large but finite group is no bad thing. If it were infinite it would seem like a cop out. Minimally we can recover what little we phenomenologically know, i.e. our current version of _The Standard Model_ by taking the subset Spin(6, 4) which is included within Spin(26, 24) given that:
      Spin(1, 3) x Spin(6, 4) → Spin(7, 7)
      it can also be shown that Spin(6, 4) includes the _Grand Unified Theory_ developed by Jogesh Pati and Abdus Salam:
      Spin(6, 4) ≅ SU(4) x ( SU(2) ‎ ‎x ‎ ‎ SU(2) ‎‎)
      ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ᴸ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎‎ ‎ᴿ
      As you can see this is non-chiral, and this undergoes spontaneous symmetry breaking to choose an apparent asymmetry of 'particles' with left handed spin in the context of the Weak interaction within our spacetime X¹·³
      SU(3) x SU(2) x U(1)
      These implicit dimensions are smuggled in using imaginary numbers (specifically the normed division algebras, which exclude the Sedenions and Trigintaduonions as it is not useful to throw away multiplicative normedness). Ordinary spacetime uses the real numbers within _General Relativity,_ however the requirement to include 'particles' with right handed spin means we need a Spin(54, ℂ) theory which has a non-compact Lorentz group L = Sl(2, ℂ) included within Spin(1, 3) as that is the double cover of SO(1, 3). The math for this is outside the scope of a UA-cam comment so I refer to the answers to this question on physics stackexchange:
      _What's the relationship between SL(2, ℂ), SU(2) x SU(2) and SO(1, 3)?_
      so now as a result of that we have recovered spacetime from the infinite meta mathematical multiverse, although there is one remaining snag: why 54? This shouldn’t be viewed as being the magic number needed to get the math to work, so although it remains an open question it is probably something to do with knots. Edward Witten took _String Theory_ in the wrong direction with his _M-theory._ This can now be seen in retrospect as a diplomatic move to bring all the five different flavours of _String Theory_ under a single multiversal umbrella by adding an 11th dimension. This can now be seen to be a mistake as he overlooked the huge clue that _Type IIB string theory_ is the only flavour which has _S-duality_ with itself. This factoid might not be that curious were it not true that this was the reason why it connected nine dimensional D9-branes which are well suited to this model (D1 ‘strings’ are insufficient and D11 branes excessive). _Type IIB string theory_ connects through the _Grand Unification of Mathematics_ which is the _Langlands Program_ and passes through _K-theory_ and _Modular Forms_ (used by Sir Andrew Wiles to prove _Fermat's Last Theorem_ ), into a connection with _Knot Theory_ which Witten has also done work on. Unfortunately, he seems to have gotten distracted by the potential benefits of knots as a representation which can undergo surgery, rather than have the intuition that the Lorentzian (1, 3) split-signature metric is the only combination of temporal and spatial dimensions in which it is possible to tie a persistent knot. It isn’t possible in a (1, 2) “Flatland”, nor is it possible in a (1, 4) ‘universe’ as there is an adjacent hyperspace that allows a ‘strand’ to slip past its bonds, in the (2, 3) case you may encounter an adjacent dimension whose parallel universe has a west coast convention and consequently the knot can go into this and reverse all of the steps by which it was knotted and appear to unravel itself as knowledge of how to do so is stored within the history of how the ‘strands’ came to be knotted in the first place.
      There is too much of a coincidence that this mathematical curiosity involving persistence operates only within our X¹·³ spacetime, which when paired with P¹·³ and quantised T you get the nine dimensions which grow the maximum set of dimensional measures needed to chart them as the Ehresmannian manifold which is initially based on Spin(54, ℂ) and as there is no other direct route from (1, 3) to any other flavour of _String Theory_ it strongly implies that those other 4 flavours describe mathematics and only _Type IIB_ has any relevance to physics. That said we still have a problem of selection, and usually Brian Greene or Sean Caroll will hand wave this away by saying all variants exist in a physical multiverse. This is unsatisfactory as it means that there are an infinite number of versions of you, so that none of your achievements have significance as other versions may be failing elsewhere. We need to be the protagonist in our own story, or at least adopt some other _Weltanschauung_ which does not undermine us existentially.
