1) The gist is this: Hologram is a 2D picture that encodes a 3D object using light interference.

Holographic principle states that information encodes reality into matter/energy and gravity. Basically gravity, matter and energy are sideffects of information. They are its projections.

How does this relate to hologram? Well dots that might appear like two separated dots on the 3D model, could be encoded on the 2D surface as very close. What this explains is "spooky action at a distance". We perceive two entangled electrons as being far away on a reality hologram, when in reality they are close on the fundamental 2D picture of the world.

Summary: What we perceive and measure as reality is not what reality fundamentally is.

NOTE: This is extremely layman termish and don't be too surprised if it's wrong. I last read UiaN years ago. There are also some other interesting properties, like that the any part of hologram contains whole picture of hologram but of lousier quality, etc.

2) I think Universe in a Nutshell covers most of this theory pretty well.

So the Celestial Spheres[1] model used by Plato, Ptolemy, etc. wasn't entirely wrong? ;)

In the same way Flatland was a real life story :)

> What this explains is "spooky action at a distance".

So what's the explanation for why almost all interactions that we perceive seem to not be spooky or at a distance?

The same reason you don't see each dot on your monitor as separate light source, unless you take a magnifying glass.

Or that you don't experience theory of relativity when accelerating.

Senses are imperfect and the information such as those aren't vital to our survival. And their effect is tiny, tiny, tiny. I'm pretty sure spooky action (iirc quantum tunneling) at a distance keeps our sun running, or at least computers.

i think you're missing the point? the original question was making the argument, i think, that if the universe is fundamentally non-local, why is almost all physics local?

using an optical analogy: if fourier space is "the real thing", why do we live in a world where point sources are much more common, useful, and interesting, than diffraction patterns?

you seem to be saying in reply "because non-local stuff is difficult to observe". but that's not an explanation; that's the problem.

[although tbh i think you could make this argument against any unified theory - it's effectively the same as "why do we get quantum decoherence?" except that now the idea that it's caused by complexity seems less intuitively right]

TL;DR. Theory of evolution meets anthropic principle

I think you are missing my point as well. Reality IS non-local, we just PERCEIVE it as local. No triangle on Earth surface has sum of angles 180, but we say - well it's close enough to 180 so lets say it's 180.

We perceive causality because it's an easier approximation than calculating probability distribution of each molecule. It's like a Russian doll, we perceive the outer doll as whole because we don't look close enough.

Because we don't need to. Evolution didn't specialize us to notice the subtle effect of quantum reality, when a good enough approximation allows us to survive and thrive. We perceive things we perceive, because of their importance for our survival. True nature of reality isn't important to our survival. Thus we don't perceive it.

Reality requires infinite amount of data to process. So we approximate it to stop being overwhelmed.

E.g. geocentric or heliocentric model of solar system are both equally valid. We just choose Heliocentric because its orbits are easier to calculate. Or earth is essentially flat even though it's a sphere etc.

> We perceive causality because it's an easier approximation than calculating probability distribution of each molecule.

That's not true. Causality is the very mode of operation of the world and it is a requirement for anything to exist at all. Without causality there would be no change and no change means no existence.

Probabilistic models only indicate the degree to which the system is not understood by the observer before his/her confirmation of the system state.

Ok, gonna be more specific, but I meant the classical notion of causality. Ball A hits ball B that hits ball C, where each effect occurred in respective chronological order that was given.

Quantuum theory proves that ball A can hit ball B that will travel back in time and hit ball C before ball B was hit. The causality isn't as narrow as in classical physics.

Also another thing to note - that all molecules in any matter move in random direction all the time, as so much their bounds allow them. It is not inconceivable that all molecules of a gold coin could simply move in the same direction and flip the coin by themselves. Chances of gold coins flipping on their own aren't impossible, just very very very very... improbable.

Sean Carroll talks a bit about this kind of problem here, (albeit when discussing the distinction between "coordinate space" and "momentum space") where we perceive the world in one way, but a lot of physics seems gears towards either one of the worldviews, and the question then is "why the hell?"

that's a good point - this is a more general issue than qm. ugh. slideshare is awful [oh; advice to expand to fullscreen makes all the difference. good slides; wish i understood more]

Well, a universe with constants that make non-local/relativistic effects common doesn't seem like it would be very good at hosting intelligent observers.

>why is almost all physics local?

Do we know that it is? Clearly we are experiencing major observation bias.

That explanation would be hidden in the formulations that describe the 10 dimensions they found.

Even though shadows in usually are short and sort of shaped like we are, though a 2d projection on the ground. When the 3d objects are in weird relations to each other the shadows can be large and deformed (spooky).

i thought every action was spooky and at a distance?

if you drop down to the smallest scales you can't tell if two things are in contact. i'm inclined to think that an infinitesemally continuous universe is an approximation we use to make the math 'easier' - in fact so are space and time - and even countability.

our best theories indicate that at small scales you can't actually tell if things are separated or not - or even if there are one or two - or even if events happen first or second.

thinking about a tiny 'almost a black hole' clock on the planck scale can reveal this very quickly with only the most basic of QM, SR and GR relations... below a certain tick rate it will collapse into a black hole and stop working, or the uncertainty effects will smear out the results so that you can't tell which tick comes first, or the error in the ticks exceeds the length of the ticks. in essense space and time are unmeasurable in the context of semi-classical QFT + GR theories

"Spooky action at a distance" implies some kind of faster-than-light phenomenon. Regular things that interact while separated by space aren't considered to have "spooky action at a distance."

Hmm.. does that mean that E=mc² is only correct for our dimension? Because, if you say that matter is a side-effect and not something like "higgs particle", then this doesn't hold up anymore. I mean not everything we don't know must exist as a particle.

I mean I believed the holographic universe theory a long time ago already, but taking it really serious, like considering it's implications to all existing findings and formulas is ripping apart my whole worldview (into a flat shape, with a lot of meta-data).

Dimension as in - three spatial dimensions we navigate every day. There is no other reality, ergo there is no our dimension.

Don't take it too literally, it's like saying information gives rise or causes energy, as in - information of the holographic universe causes energy to behave in the world we experience, probably with some other descriptions how it behaves in spaces where lower or higher dimensions are flatter than our own.
