Does Space Emerge From A Holographic Boundary?

Space seems fundamental. To build a universe, surely you need something to build it on or in. Many, maybe most physicists now think that the fabric of space emerges from something deeper. And perhaps the most existentially disturbing such proposal is that our 3-D universe is just the inward projection of an infinitely distant boundary. A hologram, or sorts. Let’s see how that can actually work, and what the holographic principle really says about the “realness” of this universe.

    I didn't fully understand this part. Is the idea that the system treats similarly shaped configurations at different scales similarly, and this creates nesting levels reality at different scales which subjectively is perceived as 3d? Again, I'm not sure if I'm understanding this correctly, but if it is then why only 3 spatial dimensions?

    That was quite interesting. Not sure how far you really can take the analogy, but coming from an IT background, that "multiple seemingly different models describing the exact same thing" made me immediately think how you (in principle) can describe an application by giving its behavior and functionality, OR by listing its source code, OR by describing how the electricity flows through the hardware circuits. Vastly different descriptions that seem to have nothing in common, yet all describing the exact same thing. Nor can you really say which of these is the "real one" as it's more a switch in your point-of-view and which description fits your purpose. If it's anything sorta-like this, yes, makes sense. Though, always have to be careful about analogies, especially when they are of something outside your own field of expertise 🙂 but can be a useful tool when trying to understand things.

    Heehee. Sometimes the ability to calculate or do math isn't the same skill as comprehending or teaching the material conceptually. Probably why I'm not in science as a career though, good with concepts and communication, would be miserable about all the mental effort it takes for me to memorize things or keep numbers straight. A Relativity class teacher once made this clear, being like, "You're the only one in the class that understands the material, but you remember two times three is six, right?" Oops. :)

    I think we continue to misunderstand space altogether. From the fact that a spin 1/2 particle needs 720 degs of rotation to come back to its starting point, to the fact that entropy is proportional to area, and that the area of a one plank volume sphere is 4 plank areas. Also, that the "stiffness" of spacetime, that defines how fast gravitational waves move through it is related, in an unknown way, the the permeability and permittivity of space. We are missing something very fundamental, IMHO, and when we find it, we'll no doubt to a face-palm.

And is this at all likely to accidentally occur?

    It feels like gravity may turn out to be the result of standing wave nodes on the surface of a blackhole which we are the projection of. Basically, Faraday waves on the boundary and we are on a sheet of time falling towards the singularity while everything we look out towards appears to be expanding. Entanglement would be the result of these nodes as they are created by a single wavefunction on the surface and are the result of all wave functions interacting to create the effect of nodes and anti-nodes. It would suggest the CMB is actually the Event horizon we are looking back towards and using it we should be able to calculate various properties of the blackhole we are in. The CMB is so uniform as things reach maximum entropy right before falling in.

    Wait, so could that also explain why we see the beginning of the universe as infinitely/extremely dense and ours is not dense in comparison? Causing us to believe our universe started off that way when it was really just the projection from the other plane and ours has a different "beginning state" that would give us different constants possibly? Where ours as it became a supermassive blackhole the total density dropped? Or am I talking nonsense, because I admit the holographic universe and this holographic boundary concept is above me, whereas usually I feel with or above the curve a little on most concepts on this channel. Could that concept you said also implicate that due to the observance of multiple black holes, would that basically be the multiverse theory in a half true manner? Except rather than concept of all possible outcomes existing and infinitely varying universal constants instead you have multiple very similar universes due to them all being black holes. Also, would the predicted ratio of matter to antimatter, and its slight imbalance, at the creation of the universe still be a relevant meaaurement? If so, I wonder in what way it would manifest itself within the concept of reality you said. Again, sorry if these are dumb questions, Im struggling with some of these concepts lol, but it weirdly feels good. The more contradictions with our theories we find with the JWST and the harder to conceptualize these topics become the giddier it makes me, for so long I think many casual followers (or maybe just myself 😅) of theoretical physics, astrophysics, astronomy, etc have felt like many of the mysteries were solved, like we were almost done or close to the final step lol. But our knowledge is like an expanding circle, as we grow the circumference of our knowledge we exponentially increase the volume of our ignorance 😂. I stole that from somewhere and probably paraphrased it crappy but you get the gist.

    This reminds me very much of a basic property of differentiable complex functions in complex analysis. If a complex function is "holomorphic" on a region - that is to say, it can be differentiated at every point both within that region as well as on the region boundary - then in fact the behavior on the boundary _alone_ is _sufficient_ to describe the entire interior behavior. The one-dimensional boundary, fills in all the details of the two-dimensional space inside it.

    I met Erik Verlinde at a Dark Matter presentation at Nanyang Technological University in Singapore thanks to my wife. One can expand on this understanding by cross-referencing his data with thousands of Boolean searches. This shows that the Bunch-Davies vacuum promotes the generation of entropy, which can be calculated within the ADS/CFT framework using the Ryu-Takayanagi proposal. This is especially clear when considering the modes that exit the horizon during inflation and contribute to the cosmic microwave background as it is today.
