Mix those thoughts with a healthy does of "human values don't necessarily have any relation to alien values, which may be just as incomprehensible to humanity as the true nature of the universe" and you've basically got the Cosmic Horror fiction genre.

and here I was trying to avoid an existential crisis today. There that goes.

Could be a dimensional thing too, what if you're like an exhibit in someone's living room like a hologram and you just live your life for someone's amusement. You'd never know but can you prove that it's happening?

Possibly dumb question, but I know my niece is going to ask me about this, and I'd like to be able to give her a solid response: does this mean that most distances within our universe are illusory? If not, why not? To expand on that thought a little bit, with a hologram, the projected object is an illusion, and can be made to appear to move at arbitrary speed by e.g. rotating the projection apparatus. On a larger sca…

My opinion is "no", because causality still exists on a 2D surface. The speed of causality will limit information from entangling with other information faster than a given rate in an offset of X or Y - if there was no limit, there'd be an infinite amount of calculations occurring on the surface in an infinitely short amount of time. You can sorta imagine it as the cells in an area of Life must be "recalculated" to fill in when you left or arrived. That certainly might translates into a different type of causality here, as it does seem that this reality is pretty intent on limiting the ability to change things here instantly.

Which reminds me of Feynman's theory that there was only one Electron and it was everywhere in the universe all at once over an infinitely long period of time, and could even travel in time if it had to.

This and Godel's Incompleteness (equivalently the halting problem) and entropy (which gives the "arrow of time") I always find endlessly strange.

what about human consciousness?

"this" was referring to human consciousness (since I was referring to a comment about that)

I don't think so. The holographic universe a "projection" in the sense that the information can be thought of as living on the boundary of a given space, with the maximum entropy / information contained therein proportional to the boundary's surface area (on a quantum level, a bit is a measurement of area ). But this isn't super shocking if you're aware of the idea of "light bubbles" (the generalisation to three dime…

The top article on that site at the moment is about the "Jewish elite". WTF? http://www.science20.com/sascha_vongehr/scientists_for_donal...

It's clearly a right-wing site.

Or at least they seem to rant against "leftist" scientists. http://www.science20.com/kevin_m_folta/the_scicomm_challenge...

Yes, but it's not the case that everything is equidistant. Allow me to illustrate with a simplified example from lower dimensions. (Warning: pseudoscientific bullshit ahead) Picture a transparent sphere, covered in tiny dots. Imagine that you live on one of these dots and the others are stars. Now, mark 'your' dot and look around on the sphere to find the dot that is farthest away, on the opposite side. If the intern…

This makes sense, but seems to be an answer to a different question about the curvature of spacetime. How does it relate to the universe being a hologram?

It doesnt. The hologram is a metaphore. Once upon a time our 3/4 dimension world was encoded upon a world with fewer dimensions LIKE a 2d hologram contains the info of a 3d image.

This world didnt last very long. Under our concept of time it happened long ago, but we can see evidence of it smeared across the sky in the cosmic microwave background. (A 2d image that should look the same no matter where you stand in our 3d space.)

A friend of mine has been trying convince me and my peers for like 2 years that the universe is holofractal. Holofractal is different than holographic [1] but is also an interesting idea.

Things like the Em Drive device and this are really making physics interesting again.

As a non physicist, there's something I don't get in the comparaison with 3d tv. From what I gathered, the only reason 3d tv is 3d is because it exploits the fact we have two eyes, distant from one another, which can provide a depth view when seeing the same thing at two different angles, or when being tricked into thinking it's that way.

What would mean a "holographic 2d space encoding 3d space" detached from an illusion made by someone observing it?

Shitty scientific journalism. Abstract says something else but who cares.

The abstract: >We test a class of holographic models for the very early Universe against cosmological observations and find that they are competitive to the standard cold dark matter model with a cosmological constant (ΛCDM) of cosmology. These models are based on three-dimensional perturbative superrenormalizable quantum field theory (QFT), and, while they predict a different power spectrum from the standard power l…

What new evidence a model brings? Model can be used to plan experiment based on it and that is evidence (once you carry out the experiment that is). Model is only used to explain how stuff is supposed to work.

Please read conclusion section of the paper.

example: Epicycles also explain how planet movement works - but it is not evidence how it works it is explanation based on data.

Distances are "illusory" to some extent anyway. On a large scale, relativity makes both time and space dependent somewhat on other factors. On a small scale, quantum mechanics similarly de-absolutizes position (space) and momentum. Space and time as absolutes appear to be a construct, a consequence of us being highly complex neural networks trained at a specific scale of the Universe - the "human scale" - as beings a…

Up or down several dozen orders of magnitude. Time and space exist for the cells in our bodies, and for mountains, moons and most stars. Time and space only break down substantially for things smaller than molicules or large enough to twist spacetime back in itself (black holes). A mouse is no further away from the moon than a dog or elephant.
