Do We Live in a Hologram? Understanding the Holographic Principle

Did you ever get that feeling that your life was a 2-dimensional representation of a 3-dimensional existence? Like a hologram? And maybe you heard that physicists have been talking about the holographic theory recently. Are we all really just living in a hologram?

Of all the people, I would expect you to clarify that 'are we living in a simulation' is NOT what holographic universe principle is about. There's a good video by Susskind, the originator of the term, on the very subject on KZbin in his quantum mechanics lectures.

[@alwaysdisputin9930]

[@Dyslexic-Artist-Theory-on-Time]

The ‘multiverses’ or extra dimensions can be explained within our 3D space by using the holographic principle in the form of positive and negative charge. Photon energy forms the movement of charge with positive and negative charge forming a two dimensional boundary condition. We have the holographic principle at work with the info of 3D space on a two dimensional surface. This geometry is formed by the two dimensional surface of the spherical harmonics. With the inner concaved surface representing negative charge and the outer convex surface forming positive charge. This forms a two dimensional boundary condition with the future unfolding photon by photon with the movement of positive and negative charge and continuous flow of electromagnetic fields.

[@PoeticBabble]

So could you store 3 dimensions in 2 then take that and store it in 1 dimension? Or would it not translate because you've already done it once?

Does the blueprint of a house count as a hologram, since it is 2D and contains the information to construct a 3D object? What about a map of the world, a written recipe for a (3D) cake, or an MRI scan - do any of those count as holograms?

[@rusty1here]

Could Erik Verlinde's theory of emergent gravity be in favour of this Holographic Principle? Also, could you explain Verlinde's theory of emergent gravity a bit more, since there's little information on it and the paper is incomprehensible.

+wil mach thanks, glad you enjoyed it

[@jedijeremy]

Thanks Fraser, and Paul! I'm glad to see a grounded treatment of the HP. I suspect you could have made the link to holographic film a little more explicit. (ie: "it's a flat sheet that, when you look through it, structures light as if a real object was in the space behind it") but I don't mind the assumption that we knew. Another "analogy" (which isn't really, just the principle at work) that I find helpful is pointing out that computer graphics / VR does the same thing, fooling you into thinking you're seeing a 3D universe through a 2D screen that's being computed by a 1D Turing machine "unspooling" it's tangled program thread. In the end you can simulate behavior in any dimension by encoding supportive structures in any other dimensional space. It's really just an expression of the true universality of Universal Turing Machines. What you lose in the process is _efficiency_, and that's a crucial point that helps cut through the philosophy - we can probe the shape of our universe by "running programs" (building experiments) and assuming it computes problems in it's "natural dimensions" faster than others. Alas, we're just starting down this road, and we've got some work to do.

[@timmccaffery4826]

Wonder if our understanding of dark energy is similar to our past understanding of another aspect of fundamental physics? And, would this insight be of some value to provide an "example" as to how our ancestors went about getting to understand that formerly "mysterious" phenomenon, and use that information to set up new tests, hypotheses, etc. to get to understand Dark Matter more. What do you think?

[@frasercain]

Right now astronomers are performing all kinds of experiments and making observations to try and understand dark matter better. They've been able to map it out with incredible detail, but they still don't actually know what it is.

Conceptually, (for explaination only) forces like gravity and magnetism are inverse squared because their (assuming point source) entire spherical surface on which the forces are acting on, grows by that much as the distance increases.

[@sheldon.s]

I've generally heard that it is impossible, and if not, very very difficult to male a perfectly accurate map of the surface of the Earth because you are bringing a 3 dimensional object down to 2 dimensions. Every map we have distorts proportions or distances or angles in some way because of this jump. How does the holographic idea work, especially in the precision needed in mathematics, if the subject could be distorted when coming down into 2 dimensions? Or do the distortions fix themselves and go back to normal after solving for whatever and translating everything back up into it's proper dimension?

[@frasercain]

Yeah, you'd need to come up with a translation system that preserves the underlying data.

Is the theory saying that the Universe is the surface of a black hole? Did this theory originate before the Matrix film or is the film based on the theory? I find it confusing that we would want to think that we are some sort of simulation but I suppose that there are ancient cultures that have speculated that we are just a dream of a god or gods.

all that did was confuse me even more. How can the surface area of a black hole increase without increasing it area/volume? As for imprinting 3 dimensions into 2 dimensions -- thats kinda easy mentally (dont ask me for the math, I haven't a clue). But I envision the bending and folding of Space-Time. same idea as two plates in plate tectonics. When they crash, Mountains go up, and Faults go down. then again, Im just a ordinary person with an over active mind.

I have a serious problem with your "Planck cube" : What is the distance between 2 opposite corners of one face, usually we would say it's around 1.41 times the length of its side, in this case 1 Planck unit, but as we cannot go below the 1 Planck unit, the asked distance only can be 1 or 2 Planck unit. Which transforms the cube in a sphere... How do scientists cope with this dilemma ?

[@WilhelmDrake]

What is the material nature of a "bit"?

[@MagicSwordKing]

I think I've got it. I'm not a scientist, I'm just a guy who is reasonably smart and knows a bunch of sciencey terms, but follow my concept here: Could it be possible that gravity and dark energy are different manifestations of the same thing, information? The Big Bang makes sense as an expansion of information, of complexity. If a bit of information takes up a defined area of two dimensional space, it would make sense that the rate of information growth would be proportional to the total complexity of the system, which is only ever increasing due to entropy. It would make sense for the universe's surface area to be at its smallest when it was most uniform, least complex. The end result would look a lot like what we observe. Or completely not. It's a fascinating topic to study, each article or video I see pushes me ever closer to conquering my disdain for math and into going back to college and actually taking up astrophysics. Quantum gravity is so interesting to me, my sense is that no matter what the solution is, it will be as massive a shift in scientific understanding as general relativity itself.

[@frasercain]

Well, in theory, the total amount of information doesn't change in the Universe, like energy, it just changes. But in theory, you can follow any piece of information back to the Big Bang. This is the whole problem with the black hole information paradox, it seems to break that rule and destroy information history. But you're right, there are deep discoveries coming that will be as important as general relativity.

[@CaliforniaMist]

Look into the mandela effect and ed mcmahon it basically proves what youre saying Ed worked for publishers clearing house there is a rap video he made about it but allegedly he never worked there.

I mean, is it possible to contribute to science without the years of mathematical & physical studies? Thx

[@frasercain]

The problem is that you need to have a deep understanding of the existing theories and what the evidence is for each one of them. Math is the language of physics and cosmology, so it's important for you to understand the math, and to be able to show why your theory better explains the nature of reality.

No but the Dunning-Kruger Effect is a hell of a cognitive bias. What makes us believe that after watching a couple short videos we might have deeper insight into a subject than ALL of the people combined who spent their lives studying that subject, wrote their PhD thesis on that subject, and who investigate that subject for a living? Why do we think that’s even in the realm of possibility?

Sounds like mathematical trickery involving complex numbers and transforms.

[@jedijeremy]

Exactly. It's why the result was so unexpected, and why the consequences are so profound. We tend to think of the "singularity" as a dot in the middle of the black-hole pudding, but in some ways there _is no space inside_, and the singularity is magnified and spread all over the event horizon. (If you're a stationary observer)

Its mirages of reality all break down under analysis." -- Paramahansa Yogananda -- "It now seems highly plausible that 'the seat of consciousness' will never be found by a neurosurgeon because it appears to involve not so much an organ, or organs, but the interaction of energy fields within the brain. These patterns of energy would be disrupted by surgical intervention, and have long since disappeared in cadavers.

I wouldn't be surprised if our entire universe is the 9D singularity of an enormous 11D black hole with a 10D event horizon surrounding us but it's behaving like a 2D horizon.

[@bobitussinX]

Holograms are when u split a laser beam, reflect half off an object and then have them intersect eachother after. At the intersection point, you need a photographic film to capture the image of the interference pattern of the 2 beams create. Then u shine the original laser at the film and the hologram becomes a 3d image of the object. We live in a black hole. The event horizon is the film with the interference pattern. The singularity projects a reference laser beam of time through the event film and our universe is revealed as a 3D hologram. Also why time only moves one way

[@bobitussinX]

It's very easy. The edge of visible universe is the inside shell of an event horizon where the 2D interference pattern is imprinted. The singularity projects time through the interference pattern to reveal the hologram. But I guess you need to understand how holography works. Our universe exists inside a black hole. As there is another universe inside every black hole

[@cliffordbotha4807]

how about the electric universe theory

[@cortster12]

4:25 If everything is separate particles, then yes: the information could be seen this way. But since everything is actually just field excitations, the information of the particles are not separate, but single, stretched phenomena. This is how Hawking radiation comes into play, since fields are on both the inside and outside of the black hole. So the sphere of excitations may be two-dimensional, but the quantum fields themselves are still very much three-dimensional and exists on both sides of the black hole. However, I do not understand how gravity affects quantum fields. But since Hawking radiation is a thing, quantum fields must remain constant through a black-hole's event horizon. Which means it is not two-dimensional.

So Opening a VR Game files in notepad?

+John Suarilla exactly

[@trevontex]

9:15 anti-derivatives?

[@1Play48]

I was thinking Laplace Transformations

[@UpcycleElectronics]

Why is the cosmic background radiation dated for 300k years specifically?

[@GODofTimewaste2]

Bike Jake Before that, the universe was too dense for photons to travel. At around 300k years, universe became "transparent", and the photons began their 13,7 billion year journey to our detectors today.

[@frasercain]

+God Of Timewaste what he said

[@vertergaminghd399]

Maybe just maybe, the quantum mechanics is applicable in 3 dimensions and as we know gravity works in more dimensions so maybe we are trying to relate to very different things

[@vertergaminghd399]

It is the string theory by the way

[@evynt9512]

At the heart of it? The back-end of the Universe. Nothing exists solely on it's own therefore we know there's a relationship to the back-end.

i really didn't understand how the event horizon can be 2 dimensional... After all It is present in our 3D space, right?

[@CraftyF0X]

Same way as a ball's surface can be thought as a 2d surface. Ofc it borders a 3d volume but the surface itself is 2d. Thats being said, handling a black hole as a "sphere" is somewhat a streach. After all, holes (at least as we undesrtand them by their everyday analoges) actually "gates" to higher dimensions in a sense. Its similar to a piece of paper (quasi 2d) with a hole, which makes nosense without considering 3d which in the hole extends to. If a balckhole is somewhat analogous to a real hole, its not even a three dimensional object but rather a "window" to a higher one. Same thing as you don't think a hole on the paper as part of the paper (or an object on a paper). Then again, analogies tends to break down at some point, and the mathematical description seems to work fine with a "quasi" surface, just as a cosmic horizon is an apparent surface as well. (arbitrary spherical slice of the 3 dimensional space)

[@dr_naVed]

CraftyF0X thanx a lot for the explanation.... (even though I confess to not understanding everything)

[@frasercain]

The surface of the event horizon is 2-dimensional, like the surface of a sphere is 2-dimensional.

[@dr_naVed]

Fraser Cain thanks a lot...

[@jerryyager2601]

Everytime the physicist says something, Fraser repeats it in in less clear terms.

[@vonvomit5666]

This sounds like the basics of time travel

[@frasercain]

I'm not sure that's the right analogy.

[@aaroncurtis8545]

Indeed: when you enter a singularity, space and time reverse roles. There's 3 dimensions of Time and one of Space; thus creating a Landscape of TIME. That's what's happening at the end of Interstellar.

[@aaroncurtis8545]

@@frasercain perhaps rewatch the end of Interstellar and read up on what that's trying to represent.

Greetings everyone. Life becomes a lot easier if you separate the idea of universe and reality. The universe (aka nature or space-time) is a given pool of information we are trying to understand. Reality is the connection between a mind and the universe, in other words perception. Typically, in perception you have a sensor taking in a snippet of the information from the universe, and sending it to a software system for analysis. Software means information stored in a memory system. So brains contain the mind software (the cortex is the containing memory system). Brains can’t directly perceive the universe (can’t create reality); only software can do that. Also, each person has constructed (via learning and experience) different mind software with which to perceive the universe. So you have different realities for all the minds connected to our universe. It should also be noted that you can create artificial informational universes out of software, and connect to that as well, just like our default universe. During the learning process our mind software expands, and we get smarter. Our perception (reality) is constantly changing because we keep adding to our mind software. This is why there is a continuum of increasing intelligence between birth and death. Thanks for listening.

[@frasercain]

+John Weck we'll put. 😀

[@JohnStephenWeck]

thanks, I hope its useful.

[@DrBiBeatz]

We could be in a simcity game kind of simulation

[@Apobothra]

What if our Universe is a lower-dimensional surface of a higher-dimensional "reality"?

[@frasercain]

+Aleksei Klimkin people have definitely thought about that. Our 3d space is actually embedded in a 4d space

[@Apobothra]

Would be interesting to see a talk on this topic given by a physicist or a cosmologist working on this kind of questions. Thanks in advance!
