Any dimension past time can only be one of thought or consciousness past "3-d" is all consciousness.... consciousness needs an "avatar" or body to experience this portion of reality. This is how you know consciousness is eternal. We could not exist if it weren't. You could say souls or consciousness are "packets" of information that have become bigger than regular "information". Cyberspace in our own network here in 3'd land is a facsimile of the "cyberspace" of "reality". WHich all consciousness flows through from the Source or God or the Truth. Scientists are trying to explain the consciousness part of reality with physical mathematics which is impossible... it cannot be represented here. Only theorized at. That's why they are called met physics.
@@MysticleMonster This is what I think through my own speculation OBVIOUSLY sorry if it seemed like I was speaking in absolutes there is no way to absolutely certain of anything outside of our 5 senses and OBVIOUSLY there are things outside of those senses and they can only be speculated upon even with tool to extend our senses we can only experience those tools through the 5 senses limitations suck I know.

respect to PBS for trying to make material like this available. Obviously you're not going to get a crystaline understanding of subjects like this in 20 meager minutes, but it's a great place to start!
You're clearly not high enough...the only way to expand your understanding is to change how you experience reality... Also, math is a language to express things not well articulated in other languages outside of programming languages, anyway. In fact, programming language may be the best way to explain this video... We are technically the code, yet we experience the virtual reality world made by the code. Our attempts to reverse engineer the code and the hardware may be impossible from our perspective, so we cheat / do it the hard way; we make models and come up with languages of it and keep reverse engineering until we make a virtual machine and code that matches.
@@Alienami I wouldn't exactly try to explain the Holographic Principle as us living in a simulation, nor reality being just a hologram. It's more the idea that our 4 perceived spatial dimensions might be in reality just 1 (I am personally not on board with this idea, which I will explain in a bit). It all basically comes down to the notion that in order for quantum mechanics to work (it is the most tested and precise science in existence), information in the universe cannot be lost. This "information" can be thought of as an equation that gives a particle causality and a somewhat defined future path -- a photon's end point location cannot really be surmised in exact details, but information in it's wave function gives you a general idea of it's end location. When matter (information) falls into a black hole, this information is seemingly lost. That kind of fubars everything that we understand about reality, time, space, even causality. Since time can be viewed as the 4th dimension, and particles (and their encoded wave function) also travel forward through time, a few theoretical physicists came up with the idea that reality might just be 1 dimensional and the 3 other dimensions we perceive just an illusion. It's doesn't mean we are living in a simulation, program, etc. A way to get around this absurd notion (at least in my mind) is to assume that all black holes have an exit... that the matter/energy/information always comes out somewhere else. This makes them not violate the 2nd law of thermodynamics. Within Eienstien's theory of Special Relativity wormholes are possible. The birth of our own universe could have been such an event -- information coming out of a white hole that is connected to a black hole through a wormhole. It's a much more elegant and simple explanation, but I don't see anyone being able to prove this unless humans can craft a machine that would survive the voyage beyond the event horizon, which is very very very very unlikely. If a probe could survive the passage and come out the other side, it probably wouldn't even end up in our universe.

Yes, you start to wonder if human science/philosophy is just going through iterations kind of like history does. String theory for example: the strings vibrate in accordance with the laws of harmonic resonance. If that reminds you of the old "Music of the Spheres" concept, you're by far not the only one. The holographic principle is also a perfect example.: there's this concept called the Akashic Records, which is generally dismissed as mystical hoo-doo, but look at what is says. It states that the entire history of the universe (our 3-D universe, that is) is recorded on a sacred scroll (that would be a 2-D surface) somewhere out in the realm of the Gods (i.e. - the farthest reaches of the creation). Are we making a scientific breakthrough, or are we just using fancy mathematics to come full circle back to what some ancient philosophers speculated?
Taoists conceptualized this well before plato. The Tao is the true reality and everything we experience is not the true Tao. We can describe an apple but we never experience the true Tao of an apple. in fact the Tao Te Ching opens with "the Tao that can be told is not the true Tao." Which means the same thing as "the universe is stranger than we CAN know"

Weyl Invariance is the most understandable explanation of multiple extra dimensions that I've ever heard and I've been interested in string theory and theoretical physics for over 10 years. Unbelieveable. I love this series.
Who is on first. We may be intuiting the 'infinitely distant' blackhole that generated us. We're intuiting our source while embedded within the generation. Infinitely distant addresses the issue of curvature. Curvature may only be relative.
Original comment is about the complexities in describing and sorting thru the possibilities that our universe is a holographic projection. The malstrom of ideas is confusing and hard to follow. In response I made a joke using a well known comic meme about misunderstanding the simple by overcomplicated misinterpretation. What I said was we are inside of and a part of the holographic projection trying to figure out how that projection works. I then state the issue of the curvature nature of the projection may only be dependant on and relative to where the observer is. I am saying the projector of our holographic universes is a 'black hole' of a kind.

@TROPICAL SUMMER IS COMING FOR THOSE WHO GET IT!!! dude, why are you shouting? Do you live on a planet where no one can be heard unless they shout over everyone else? Or are you just loud?
Yeshua Immanuel Christ 🐟 05. THE PHENOMENAL UNIVERSE: The fact that the external, phenomenal universe (“prakṛti”, in Sanskrit) of names and forms (“nāmarūpa”, in Sanskrit/Pali) exists solely within personal consciousness (and by extension, Universal Consciousness), is superlatively logical. If this material world actually existed as a separate reality, then obviously, it would have limits, because the nature of matter is that it has a measurable, three-dimensional finitude. Therefore, if one were to travel to the edge of the universe, there would need to be something WITHOUT the boundary of the universe (some other ’’universe’’, which contains this universe). This contradicts the very concept of a universe (literally, “turned into one”). The late, great Professor Dr. Alan Watts’ response to the question: “where is the universe located?”, was: “nowhere and everywhere”. This phenomenal manifestation is composed of space, time, energy, and matter, the latter of which comprises eight elemental groups - the five GROSS elements (“mahābhūta”, in Sanskrit), which are perceivable by at least one of the five senses, and the three SUBTLE elements (“tanmātra” or “atisūkṣma mātra”, in Sanskrit), which are symptomatic of localized consciousness. N. B. Dark matter is not included in this system, as cosmological science has yet to determine its structural composition. The five gross material elements and three subtle material elements are (from most gross to most subtle): SOLIDS (AKA earth - “bhūmiḥ” or “pṛthivī”, in Sanskrit) are made of densely-packed atoms and molecules of a steady shape at room temperature. LIQUIDS (AKA water - “jala” or “āpaḥ”, in Sanskrit) are composed of moderately dense molecules (usually including at least some water) of no fixed shape. GAS (AKA air - “vāyuḥ” or “marut”, in Sanskrit) consists of rarefied atomic particles of no fixed shape. HEAT (AKA fire - “analaḥ” or “tejas”, in Sanskrit) is made of kinetic energy (which may or may not appear visibly as fire, or at least heat waves). ETHER (AKA space - “ākāśa” or “khaṃ”, in Sanskrit) is a vacuum consisting of three-dimensional space (length, breadth, and width). However, recent investigation has confirmed that empty space is actually filled with virtual particles (matter and antimatter). Thus, the explanation for the material universe being created from “nothing” (anti-matter) is plausible, according to quantum field theory. MIND (“manaḥ”, in Sanskrit) is composed of sensual perceptions, instinctual thoughts, abstract images (including memories and fantasies), and emotions. Not all animal species possess a mind, but function purely on base instincts, originating from their genetic code, via a rudimentary nervous system. INTELLECT (“buddhiḥ”, in Sanskrit) consists of conceptual thoughts. Only the very higher species of animal life possess an intellectual capacity. PSEUDO-EGO (“ahaṃkāraḥ”, in Sanskrit) is comprised of the “I” thought (in this case, the illusory, ephemeral self-identity). Only humans possess the self-awareness necessary to question their own existence. Read Chapter 10 for a full elucidation of egoity. Each of the FIVE gross material elements corresponds to one of the senses of the body. E.g. In outer space, where there is a vacuum (ether), one can detect light with the eyes, yet space is not tactile and cannot be smelled or tasted, nor can sound waves travel via space. At the opposite extreme, solid matter can be seen with the eyes, felt with the sense of touch, tasted with the tongue, smelt with the nose, and heard with the ear (when the solid matter is physically vibrated). Beyond these eight material elements is the TRUE self - which pervades the entire body, and indeed, which is the Universal Self (“ayam ātmā brahma”, in Sanskrit). That explains why we say: “This is my body” or “I possess a mind”. Who is the owner of the body and the mind? It is us, the anti-matter, the inextinguishable authentic self/Self (“ātmana/Paramātmana”, in Sanskrit). Ultimately speaking, the Universal Self alone is. HOWEVER, all eight elements are in fact “made” of Consciousness, since, as demonstrated previously, naught but Consciousness exists. Consciousness is the ultimate reality (“prajñānam brahma”, in Sanskrit). Just as a wedding ring is contingent on gold for its very existence, so too does the phenomenal universe depend entirely on ”Beingness” or “Isness”, Consciousness, and Blissful Awareness. Although The Absolute cannot be verbally-described, (otherwise, it would be an OBJECT), as a concession to materialists, Infinite Consciousness has said to exhibit three innate attributes, known as “sacchidānanda”, a compounded Sanskrit epithet, consisting of the three words “sat”, “cit” and “ānanda” - Eternal Being(ness), Existence, or Truth; Conscious Knowledge; and Perfect Peace (often translated as “bliss”. However, the term “bliss” connotes an ephemeral experience of euphoria, whereas “peace” is the absence of any form of temporal suffering). Because Absolutely Nothing (“Brahman”, in Sanskrit) is Infinite Creative Potentiality, ‘it’ actualizes as Absolutely Everything. Attributeless Consciousness at Rest (in Sanskrit, “Nirguna Brahman”) manifests as this phenomenal universe (Consciousness in Action, or in Sanskrit, “Saguna Brahman”). In the verbiage of quantum physics, the enfolded implicate order ‘becomes’ the unfolded explicate order. In REALITY there is no separation of anything at any time (assuming that Consciousness is a “thing”, and that time is an attribute of The Uncaused Absolute). That the total sum energy of the universe is zero, implies the non-existence of matter (i. e. no thing is objectively real). The phenomenal manifestation is eternally cyclical, because ‘coming into existence’ implies ‘going out of existence’, just as ‘black’ implies the existence of ‘white’, or as ‘rich’ implies ‘poor’. Is it possible to have something without nothing? Obviously not, because the two go together, as interrelated opposites. Similarly, despite what most believe, the outer-world is as much the Self as the inner-world. Where is the boundary of the human body? When we look at a person, we cannot see that person UNLESS we also see the background image. The two are inseparable, just as a flower and a bee cannot exist without the other. This fact alone is ample evidence that the universe is a holistic and wholistic system or entity. You who are reading these words are that Totality of Existence, the Highest Universal Principle, the Essential Irreducible Self. In common parlance, you are God (IF you only knew it!). Most of the greatest sages in history have spoken about either or both these concepts (of the Absolute Truth being either Absolutely Everything or Absolute Nothingness), such as the concept of “form is emptiness and emptiness is form” in Buddhism, or in Avatar Meher Baba's book “The Everything and the Nothing” (which is highly-recommended, particularly Chapters 51 to 56, which poetically describe the Ineffable One-without-a-second). Even an ordinary writer, American author Kurt Vonnegut, once penned: “Everything is nothing - with a twist”. The Stanford Institute for Theoretical Physics professor, Doctor Leonard Susskind's so-called “minus-first law of physics” states that information is INDESTRUCTIBLE. This is akin to the law of conservation of energy in classical physics, and proves that neither physical or psychic energy is lost. Read subsequent chapters to learn more about how this law relates to the notion of reincarnation, as well as to miraculous phenomena such as savant syndrome. The planet on which we are residing consists of animate/organic life, as well as inanimate/inorganic matter. The six stages of ORGANIC life are: 1. conception/birth 2. growth/development 3. maintenance 4. reproduction 5. ageing/deterioration 6. death British polymath Thomas Young's famous double-slit experiment suggests that matter exists purely as potentiality or as a "possibility" until it is observed by a conscious being. This phenomenon, known as the wave-particle duality, is often discussed in advanced spiritual discourses, as it gives credence to the primacy of Consciousness. There are other aspects of the universe (e.g. the various philosophical approaches to the nature of ontological time, the accelerated expanding universe, holographic universe principle, quantum superposition, wave function, and quantum entanglement), as well as the possibility of life on other planets, the crop circle phenomenon, and the presence of the Fibonacci sequence in nature, which are beyond the scope of this document, and which do not directly relate to the most exigent thing in life (to find the unending peace/happiness which we humans are ULTIMATELY seeking).
“Find out who you REALLY are so that when death comes…there is no-one to kill, for while you are identified with your role, with your name, with your ego, there is someone to kill. But when you are identified with the whole universe, death finds you already annihilated and there’s no-one to kill”. ************* “Just as you depend on the universe, so too does the universe depend on YOU. Everything depends on everything else.” Professor Alan W. Watts, British-American Philosopher.

Math. You can conceptually simplify complex realities using math. That's why so much of new physics started as a way to get the math right. Like adding string length as a 4th dimension.

So could that dual representation be taken a step further to having a representation in every dimension? Even going beyond 4D, to 5D, 6D, an infinite amount of times? Also would there be such a thing as having no dimension, or is that a singularity?
An astonishing good comprehensible, though deep explanation. Another hint of the holographic principle (similar to the Bekenstein entropy) is that the event horizon of a black hole is proportional to its mass and NOT proportional to the third root of its mass.
Another hint: If you took all the mass-energy of the observable universe, and compressed it to a point to create a black hole, the Schwarzschild radius of that black hole would be the cosmic event horizon.

@The Jim Reaper™ If the universe is holographic, it always was holographic so there is no aparent difference for us. The only real change would be our understanding of fundamentals of our universe, which would allow us to create new technology that could make life better (or end it.. whatever the intention is).

@@amartya-w3i Thanks for engaging. I noticed the calculation from the CMB argument later, when I did some google searching. Still though, it seems odd that the CMB shows a flat universe while far away galaxies are accelerating away from us faster and faster, like they are falling off a far away curve in spacetime. We could maybe explain both if it turned out that we just weren't thinking about the way that the expansion of space interacted with the CMB correctly. It is more likely that I just don't understand though.
@@amartya-w3i who cares about calculus. The question was about reality, which can only be measured. Currently, the Universe appears to be flat, but we have only measured down to about the 0.4% level. To actually test the curvature we need distances hundreds times larger than the observable Universe.

This video proved I'm dumb in every dimension.
Any dimension past time can only be one of thought or consciousness past "3-d" is all consciousness.... consciousness needs an "avatar" or body to experience this portion of reality. This is how you know consciousness is eternal. We could not exist if it weren't. You could say souls or consciousness are "packets" of information that have become bigger than regular "information". Cyberspace in our own network here in 3'd land is a facsimile of the "cyberspace" of "reality". WHich all consciousness flows through from the Source or God or the Truth. Scientists are trying to explain the consciousness part of reality with physical mathematics which is impossible... it cannot be represented here. Only theorized at. That's why they are called met physics.

Also, math is a language to express things not well articulated in other languages outside of programming languages, anyway.
In fact, programming language may be the best way to explain this video...
We are technically the code, yet we experience the virtual reality world made by the code.
Our attempts to reverse engineer the code and the hardware may be impossible from our perspective, so we cheat / do it the hard way; we make models and come up with languages of it and keep reverse engineering until we make a virtual machine and code that matches.
@@Alienami I wouldn't exactly try to explain the Holographic Principle as us living in a simulation, nor reality being just a hologram. It's more the idea that our 4 perceived spatial dimensions might be in reality just 1 (I am personally not on board with this idea, which I will explain in a bit). It all basically comes down to the notion that in order for quantum mechanics to work (it is the most tested and precise science in existence), information in the universe cannot be lost. This "information" can be thought of as an equation that gives a particle causality and a somewhat defined future path -- a photon's end point location cannot really be surmised in exact details, but information in it's wave function gives you a general idea of it's end location. When matter (information) falls into a black hole, this information is seemingly lost. That kind of fubars everything that we understand about reality, time, space, even causality. Since time can be viewed as the 4th dimension, and particles (and their encoded wave function) also travel forward through time, a few theoretical physicists came up with the idea that reality might just be 1 dimensional and the 3 other dimensions we perceive just an illusion. It's doesn't mean we are living in a simulation, program, etc.
A way to get around this absurd notion (at least in my mind) is to assume that all black holes have an exit... that the matter/energy/information always comes out somewhere else. This makes them not violate the 2nd law of thermodynamics. Within Eienstien's theory of Special Relativity wormholes are possible. The birth of our own universe could have been such an event -- information coming out of a white hole that is connected to a black hole through a wormhole. It's a much more elegant and simple explanation, but I don't see anyone being able to prove this unless humans can craft a machine that would survive the voyage beyond the event horizon, which is very very very very unlikely. If a probe could survive the passage and come out the other side, it probably wouldn't even end up in our universe.

This reminds me of Plato's concept of the world we experience as a mere shadow, or projection, of the ultimate reality.
I think you're onto something
Yes, you start to wonder if human science/philosophy is just going through iterations kind of like history does. String theory for example: the strings vibrate in accordance with the laws of harmonic resonance. If that reminds you of the old "Music of the Spheres" concept, you're by far not the only one. The holographic principle is also a perfect example.: there's this concept called the Akashic Records, which is generally dismissed as mystical hoo-doo, but look at what is says. It states that the entire history of the universe (our 3-D universe, that is) is recorded on a sacred scroll (that would be a 2-D surface) somewhere out in the realm of the Gods (i.e. - the farthest reaches of the creation).
Are we making a scientific breakthrough, or are we just using fancy mathematics to come full circle back to what some ancient philosophers speculated?
Taoists conceptualized this well before plato. The Tao is the true reality and everything we experience is not the true Tao. We can describe an apple but we never experience the true Tao of an apple. in fact the Tao Te Ching opens with "the Tao that can be told is not the true Tao." Which means the same thing as "the universe is stranger than we CAN know"

Original comment is about the complexities in describing and sorting thru the possibilities that our universe is a holographic projection. The malstrom of ideas is confusing and hard to follow.
In response I made a joke using a well known comic meme about misunderstanding the simple by overcomplicated misinterpretation.
What I said was we are inside of and a part of the holographic projection trying to figure out how that projection works. I then state the issue of the curvature nature of the projection may only be dependant on and relative to where the observer is.

🐟 05. THE PHENOMENAL UNIVERSE:
The fact that the external, phenomenal universe (“prakṛti”, in Sanskrit) of names and forms (“nāmarūpa”, in Sanskrit/Pali) exists solely within personal consciousness (and by extension, Universal Consciousness), is superlatively logical. If this material world actually existed as a separate reality, then obviously, it would have limits, because the nature of matter is that it has a measurable, three-dimensional finitude. Therefore, if one were to travel to the edge of the universe, there would need to be something WITHOUT the boundary of the universe (some other ’’universe’’, which contains this universe). This contradicts the very concept of a universe (literally, “turned into one”).
The late, great Professor Dr. Alan Watts’ response to the question: “where is the universe located?”, was: “nowhere and everywhere”.
This phenomenal manifestation is composed of space, time, energy, and matter, the latter of which comprises eight elemental groups - the five GROSS elements (“mahābhūta”, in Sanskrit), which are perceivable by at least one of the five senses, and the three SUBTLE elements (“tanmātra” or “atisūkṣma mātra”, in Sanskrit), which are symptomatic of localized consciousness.
N. B. Dark matter is not included in this system, as cosmological science has yet to determine its structural composition.
The five gross material elements and three subtle material elements are (from most gross to most subtle):
SOLIDS (AKA earth - “bhūmiḥ” or “pṛthivī”, in Sanskrit) are made of densely-packed atoms and molecules of a steady shape at room temperature.
LIQUIDS (AKA water - “jala” or “āpaḥ”, in Sanskrit) are composed of moderately dense molecules (usually including at least some water) of no fixed shape.
GAS (AKA air - “vāyuḥ” or “marut”, in Sanskrit) consists of rarefied atomic particles of no fixed shape.
HEAT (AKA fire - “analaḥ” or “tejas”, in Sanskrit) is made of kinetic energy (which may or may not appear visibly as fire, or at least heat waves).
ETHER (AKA space - “ākāśa” or “khaṃ”, in Sanskrit) is a vacuum consisting of three-dimensional space (length, breadth, and width). However, recent investigation has confirmed that empty space is actually filled with virtual particles (matter and antimatter). Thus, the explanation for the material universe being created from “nothing” (anti-matter) is plausible, according to quantum field theory.
MIND (“manaḥ”, in Sanskrit) is composed of sensual perceptions, instinctual thoughts, abstract images (including memories and fantasies), and emotions. Not all animal species possess a mind, but function purely on base instincts, originating from their genetic code, via a rudimentary nervous system.
INTELLECT (“buddhiḥ”, in Sanskrit) consists of conceptual thoughts. Only the very higher species of animal life possess an intellectual capacity.
PSEUDO-EGO (“ahaṃkāraḥ”, in Sanskrit) is comprised of the “I” thought (in this case, the illusory, ephemeral self-identity). Only humans possess the self-awareness necessary to question their own existence. Read Chapter 10 for a full elucidation of egoity.
Each of the FIVE gross material elements corresponds to one of the senses of the body. E.g. In outer space, where there is a vacuum (ether), one can detect light with the eyes, yet space is not tactile and cannot be smelled or tasted, nor can sound waves travel via space. At the opposite extreme, solid matter can be seen with the eyes, felt with the sense of touch, tasted with the tongue, smelt with the nose, and heard with the ear (when the solid matter is physically vibrated).
Beyond these eight material elements is the TRUE self - which pervades the entire body, and indeed, which is the Universal Self (“ayam ātmā brahma”, in Sanskrit). That explains why we say: “This is my body” or “I possess a mind”. Who is the owner of the body and the mind? It is us, the anti-matter, the inextinguishable authentic self/Self (“ātmana/Paramātmana”, in Sanskrit). Ultimately speaking, the Universal Self alone is.
HOWEVER, all eight elements are in fact “made” of Consciousness, since, as demonstrated previously, naught but Consciousness exists. Consciousness is the ultimate reality (“prajñānam brahma”, in Sanskrit). Just as a wedding ring is contingent on gold for its very existence, so too does the phenomenal universe depend entirely on ”Beingness” or “Isness”, Consciousness, and Blissful Awareness.
Although The Absolute cannot be verbally-described, (otherwise, it would be an OBJECT), as a concession to materialists, Infinite Consciousness has said to exhibit three innate attributes, known as “sacchidānanda”, a compounded Sanskrit epithet, consisting of the three words “sat”, “cit” and “ānanda” - Eternal Being(ness), Existence, or Truth; Conscious Knowledge; and Perfect Peace (often translated as “bliss”. However, the term “bliss” connotes an ephemeral experience of euphoria, whereas “peace” is the absence of any form of temporal suffering).
Because Absolutely Nothing (“Brahman”, in Sanskrit) is Infinite Creative Potentiality, ‘it’ actualizes as Absolutely Everything.
Attributeless Consciousness at Rest (in Sanskrit, “Nirguna Brahman”) manifests as this phenomenal universe (Consciousness in Action, or in Sanskrit, “Saguna Brahman”). In the verbiage of quantum physics, the enfolded implicate order ‘becomes’ the unfolded explicate order.
In REALITY there is no separation of anything at any time (assuming that Consciousness is a “thing”, and that time is an attribute of The Uncaused Absolute). That the total sum energy of the universe is zero, implies the non-existence of matter (i. e. no thing is objectively real).
The phenomenal manifestation is eternally cyclical, because ‘coming into existence’ implies ‘going out of existence’, just as ‘black’ implies the existence of ‘white’, or as ‘rich’ implies ‘poor’. Is it possible to have something without nothing? Obviously not, because the two go together, as interrelated opposites.
Similarly, despite what most believe, the outer-world is as much the Self as the inner-world. Where is the boundary of the human body? When we look at a person, we cannot see that person UNLESS we also see the background image. The two are inseparable, just as a flower and a bee cannot exist without the other. This fact alone is ample evidence that the universe is a holistic and wholistic system or entity.
You who are reading these words are that Totality of Existence, the Highest Universal Principle, the Essential Irreducible Self.
In common parlance, you are God (IF you only knew it!). Most of the greatest sages in history have spoken about either or both these concepts (of the Absolute Truth being either Absolutely Everything or Absolute Nothingness), such as the concept of “form is emptiness and emptiness is form” in Buddhism, or in Avatar Meher Baba's book “The Everything and the Nothing” (which is highly-recommended, particularly Chapters 51 to 56, which poetically describe the Ineffable One-without-a-second). Even an ordinary writer, American author Kurt Vonnegut, once penned: “Everything is nothing - with a twist”.
The Stanford Institute for Theoretical Physics professor, Doctor Leonard Susskind's so-called “minus-first law of physics” states that information is INDESTRUCTIBLE. This is akin to the law of conservation of energy in classical physics, and proves that neither physical or psychic energy is lost. Read subsequent chapters to learn more about how this law relates to the notion of reincarnation, as well as to miraculous phenomena such as savant syndrome.
The planet on which we are residing consists of animate/organic life, as well as inanimate/inorganic matter.
The six stages of ORGANIC life are:
1. conception/birth
2. growth/development
3. maintenance
4. reproduction
5. ageing/deterioration
6. death
British polymath Thomas Young's famous double-slit experiment suggests that matter exists purely as potentiality or as a "possibility" until it is observed by a conscious being. This phenomenon, known as the wave-particle duality, is often discussed in advanced spiritual discourses, as it gives credence to the primacy of Consciousness. There are other aspects of the universe (e.g. the various philosophical approaches to the nature of ontological time, the accelerated expanding universe, holographic universe principle, quantum superposition, wave function, and quantum entanglement), as well as the possibility of life on other planets, the crop circle phenomenon, and the presence of the Fibonacci sequence in nature, which are beyond the scope of this document, and which do not directly relate to the most exigent thing in life (to find the unending peace/happiness which we humans are ULTIMATELY seeking).
“Find out who you REALLY are so that when death comes…there is no-one to kill, for while you are identified with your role, with your name, with your ego, there is someone to kill. But when you are identified with the whole universe, death finds you already annihilated and there’s no-one to kill”.

@Enter the Bragn’ you're not the one to say that, and even if it's wrong (and again, you're not the one who determine that), you need to appreciate the math and the logic behind it
@Enter the Bragn’ 😂😂 you made me laugh lol, Honestly, If the explanation of the universe is less complicated than this, I'd be doubtful of it, because the universe is complex in itself.
Enter the Bragn’ a very smart man will one day explain the universe in an essay and that’s as simple as it will get..
hahaha
"If anyone feels like drawing Roger Penrose dressed as Gandalf with a lightsaber and a TARDIS, you would win the internet."
Actually quantum mechanics forbids this.
I want to say challenge accepted, but I suck at drawing 😥
I really want to take you up on this challenge.... But in all reality isn't Penrose, Gandalf and Yoda the same thing? And wouldnt that just make it all redundant anyway? Or am I just too lazy to draw right now lol.
Evidently a blogspot user called Peterscartoons has won the internet. We can all stop now.
So could that dual representation be taken a step further to having a representation in every dimension? Even going beyond 4D, to 5D, 6D, an infinite amount of times? Also would there be such a thing as having no dimension, or is that a singularity?
The music makes me feel like I'm underground in a mario level
It reminds the music of some levels in an Asterix the Gaelic's snes game.

Nice use of “The Game Of Life” as an illustration.

An astonishing good comprehensible, though deep explanation. Another hint of the holographic principle (similar to the Bekenstein entropy) is that the event horizon of a black hole is proportional to its mass and NOT proportional to the third root of its mass.
Another hint: If you took all the mass-energy of the observable universe, and compressed it to a point to create a black hole, the Schwarzschild radius of that black hole would be the cosmic event horizon.
After you are done with Cosmology, how about an episode on quantum loop gravity?
I second.
Please!
Amen! And if you do one, please explain a bit about how discrete spacetime helps us get rid off the divergences in QFT without renormalisation.
@@LuisAldamiz third
Agree. I would watch episodes about other quantum gravity candidates too.
**At one point i noticed the expression on my face that i had...**
"The tension on my facial muscles was so high due the concentration and the huge effort that i was putting in of trying to understanding the sentences and the words that it was constructed from, plus trying to keep up with the next... and the next sentence.., then making more effort to glue them together and get somewhat a picture of what was been presented to me, or what i had to envision with this presentation/explanation that when i saw "bananas", i just ran out of RAM..."
**Quietly i hit the like button like a good boy...**
Jinxed When the screen suddenly went black I caught a mirror image of myself. What I saw was every muscle in my face going slack and my jaw hanging and my mouth gaping. I was breathing through my mouth and my eyes looked vacant. I feel a need to go dig a hole in the dirt.
(My thoughts, at the beginning: Great, now to understand this stuff...
My thoughts, at the end: When is he going to start explaining this stuff...)
Ditto
i never understand any shit on this channel, still like it though. I think it's soothing and often fall asleep by it.
You made me laugh because sometimes I start one of these videos just for the purpose to help me fall asleep :D
Lol. Though I watch these videos to actually understand them, not to sleep :D
Dude the music is absolutely amazing , mind blown
So... you CAN judge a book by its cover?
Only if all of the contents of the book appear on the cover.
If it's been compressed so much that it's turned into a black hole, sure... Hope you like radiation with such a small black hole though 😙
@@fattyMcGee97 black hole with the mass of a book ? Haha, BOOOOM
William Smith when I was in 5th grade my teacher told me the same thing. Judge a book by its cover, usually the outside reflects what’s within.
nice one XD
You make all of this so much easier to conceptualize, appreciate it sir!
This is the most developped flat earth theory
It's complete with weird suspenseful music and a line " ...or is it?"
@@boboblacksheep5003 Yes!! Even his t-shirt. So glad I read the comments, I'm getting less angry every comment.
This video is special, he explained such a mind-boggling concept, so well, that even a layman like me can follow
Nobody:
PBS: An abstract mathematical surface, infinitely far from our location and from our intuition. Projecting inwards our familiar holographic space time.
I watched all the vids leading up to this one by one as many times as it took for me to fully understand them. Now I can understand this and I'm so glad. Awesome stuff thanks for the series
@Yeshua Immanuel Christ Sure, can you send me the book?
I was halfway through this before I realised my mouth was hanging open.
love the background track in this one. props to the sound mixer
I understand every word of this.
Every word.
At least up to the first few seconds.
@Brian O'Kongkohr Aha! Ok, thank you for clearing this up!
I understood every word but once he assembled them into sentences I got lost.
Yes, I feel the same way.
I know what the individual words mean, and that's where it ends.
I think it's a pronunciation issue.
I understand every word... if I analyze them separately, and not as being part of a multi...verse.
To say this is tough stuff is an understatement. Here is my advice:
1. Watch this thing on repeat until it clicks. or...
2. Put the playback speed at .75 or even .5
This probably one of the hardest episode in space time episode 🤪🤪🤪. Only 10 minutes in the video and i alr give up...
It's because science fiction is not always easy to understand. These assholes think they're being creative when drumming up this bullshit.
@@Mick0722MX IT SOUNDS LIKE IT TICKS YOU OFF WHEN YOU DON'T UNDERSTAND SOMETHING.
@@hiker919 I understand it perfectly, moron. That's why I'm criticizing it. What's your excuse?
The outro to this was incredible. Earned my like.
Flat Earthers: Scientists lie, the Earth is Flat
Most people: The earth is not flat
Scientists: The universe does appear to be flat
Everyone:
By "does appear" you mean "is seems, but we aren't sure", right?
the earth is a very far cry from the universe though dude
@@twilightsparkle75
It's a joke, they believe divine energies lift the "flat earth" "up" through the universe lol.
It sure would be ironic in every way imaginable if they started quoting scientists saying the universe is flat though xD
Stars are white holes. I could see where you'd think it was flat.
Stars form from collapsing gas and dust mostly. Stars like our sun aren't even big enough to collapse into a black hole let alone be ejection from a white hole.
If there is such a thing as a white hole, quasars would be a much more likely candidate than any known star
Everyone talking about M87 black hole
PBS Space Time : holographic universe
Dr Becky incomming. (I think)
This is theoretical physics. M87 is Black Hole Engineering with the Black hole showing us all it’s sides at once.
SpaceTime isn't boring us with press releases!
I believe black holes were already covered.
They will probably do a journal club on in about a month and a half.
This explains why I have been struggling in school ever since they introduced the z axis...🙄 It's just not native to our universe.
🧏🏽♀️
...The z axis is our universe
Do you know your comment is the most sensible in this lot?
@@muhaiminurrahman4288 yeah. I don't get the ignorance here. It doesn't take a genius to realize that our universe exists in forward to back, left to right, and up and down
@@thebboi3339 I was actually referring to @Who Dis?
Edit: However, yours is sensible too. I guess we are at that point in time where you can say anything about the universe and find subsequent theories to uphold your claim! Mad times these are!
I never thought I'd get a great intuitive sense of the mechanism underlying AdS/CFT correspondence, but Matt rose to the challenge. Not for the first time! 😎
I get so excited that I have to pause the video every now and then to calm down
At ~ one minute in, I paraphrase: "The concept of a holographic universe is complex, and over past few months, we've built up to it with the following six videos. You might want to go watch those first, in order, before watching this one".
My response: Watch this one, then the immediately preceding one, back up to the original, in reverse order.
My recommendation: Don't be an idiot! That is NOT the right way to do it. You're probably a lot more sensible than I and don't need to be told that, but just in case: Start at the beginning, and move forwards towards this. They're interesting, well-done, and help enrich understanding once you DO get to this one.
Ok, I will need to rewatch this one.
... a thousand times or until my brain explodes, whatever happens first.
Guys doing the animations here, editing and music have great skills.
I feel like someone is slapping my brain while watching and trying to understand this.
Don't worry. That's how it started for most of us, but with enough videos you start to understand more and more.
Except for string theory of course. If you think you understand string theory, you do not understand string theory xD
@The Jim Reaper™ If the universe is holographic, it always was holographic so there is no aparent difference for us.
The only real change would be our understanding of fundamentals of our universe, which would allow us to create new technology that could make life better (or end it.. whatever the intention is).
But we do not really know how these would look like yet. It'd just be a new chapter in science.
LOL!!!! Not just me then.
@@liquidminds just like most foundational physics, I don't think this will have any repercussions for technology (except indirectly in the development of test equipment or faster computers). Stuff like this is much more important than just progressing technology anyway- this is what progression in technology and mathematics is FOR.
liquidminds nah those string theory videos had me fucked up for a full week
Please do a video in depth explation of the 1st black hole photo
Event Horizon project was made, bunch of dudes said, "Let's photo a blackhole!", M87's SM Blackhole happened to have a cloud of gas in its vicinity, gas fell into the blackhole, gas orbited the blackhole which caused it to heat up and glow, glowing gas shows the "shadow" of the blackhole, and Event Horizon project takes the image. Nerds (including myself) everywhere have an orgasm.
@@FirstLast-zv5od everyone here knows that. We want to know how?
Dirk from Veritasium has made 2 very good videos explaining it.
@@Nilguiri Good videos but many questions remain. Is there a singularity? Or are black holes fuzzy (string theory) balls of strings jammed together? As an object falls towards a black hole and is accelerated to light speed (almost) where does its kinetic energy come from? Is spacetime itself sucked into a black hole? What about dark matter?
Agreed :)
holographic universe and computer codes in string theory mean that the Matrix may not be that far off
Probably gonna be more like a Weyl tensor than a matrix. Matrices are actually pretty dull.
Keep watching to the end. This guy is good.

What a smart guy
This is the most beautiful physics I have ever seen. It's pure transcendence.
This channel and content is invaluable to humanity! Thank you, Matt and Team!
Gotta hand it to you Mark, you not only got me to where the holographic universe notion finally made sense for me (previous week's video) but gave me enough to jump ahead into some interesting further ideas.
Saying, "in good old string theory style" like he's talking about his buddy Steve who always loses his keys. "Oh, you know lol, classsssic Steve"
Why do we know that we don't live in an ADS space? Wouldn't hyperbolic spatial curvature make far away galaxies appear to accelerate, just like dark energy does?
kawikapful ads is negatively curved, our universe is flat from calculations.
@@amartya-w3i Thanks for engaging. I noticed the calculation from the CMB argument later, when I did some google searching. Still though, it seems odd that the CMB shows a flat universe while far away galaxies are accelerating away from us faster and faster, like they are falling off a far away curve in spacetime.
We could maybe explain both if it turned out that we just weren't thinking about the way that the expansion of space interacted with the CMB correctly. It is more likely that I just don't understand though.
@@amartya-w3i who cares about calculus. The question was about reality, which can only be measured. Currently, the Universe appears to be flat, but we have only measured down to about the 0.4% level. To actually test the curvature we need distances hundreds times larger than the observable Universe.
@@amartya-w3i is there no way it could exist without negative curvature?
The title of this video should be "Making Holographic Universe Theory even harder to understand". I'll wait for Don Lincoln's explanation on this.
A way to understand this is to think of it like vr. You have computer code that is 2 dimensional which appears to have depth (3 dimensions) when you put it on. In vr, things look 3 dimensional even though it’s made of 2d code
I love watching videos about the universe. But sadly I can only absorb 1% lol
I'm writing a paper on this and this video helps so freaking much, thank you!!
Me too. Which university are you in and can you show me some relevant papers?
Can you try to explain us the hologram theory?
@@schmirgldecks It's the theory that Flat-Earthers may like. Because our 3D universe could be 2D. All the information required to describe the 3D universe can be encoded on a 2D surface.
black holes are texture glitches in the matrix, got it.
Thank you
