I cant tell if all of the comments here are genuine, or the output of some high performance markov chains. Also, i have absolutely no ability to penetrate what is being described by this article. Holograms work by applying lasers to different surfaces and re-rendering the image relative to the original laser's point of view. How does the word 'holographic' apply?

Holograms are 2d images that look 3d from our perspective. Similarly, this theory is that our perceived reality of 3 spatial dimensions + time is actually fully contained on a 2d surface.

Thank you for taking the time to try to educate me.

I think that this metaphor is flawed. Holograms project an illusion of depth, but they clearly are not 3 dimensional. The metaphor falls apart if your thought process includes the assumption that eyesight is an unreliable depth detector.

There are other methods for detecting x/y/z coordinates that do not rely on eyesight- consequently, I'm having a hard time reconciling what the metaphor describes.

I feel that Platz's material below is more descriptive and helps communicate the concepts in a far less confusing way.

Is this actually evidence or lack of proof against?

The abstract says: > We test a class of holographic models for the very early universe against cosmological observations and find that they are competitive to the standard ΛCDM model of cosmology. These models are based on three dimensional perturbative super-renormalizable Quantum Field Theory (QFT), and while they predict a different power spectrum from the standard power-law used in ΛCDM, they still provide an exc…

Hmm, this actually makes me much more excited. I finished with grappling existential issues about being a simulation a long time ago; I don't see the point anymore. But if I understand this right, this would give us reason to believe we could simulate absolutely tiny models of the universe with relatively high (still quite low) confidence it's meaningful. Is that fair?

Time and space does not exist for a mountain. Time and space are first and foremost concepts (ideas, opinions, "facts") Have you tried asking a mountain whether it ascribes the state "exist" to the concepts of time and space? It is true that time and space exists for humans thinking about the mountain however.

> Time and space does not exist for a mountain. Time exists for the mountain. The mountain moves through time and is effected by time. The mountain is incapable of perceiving time. Neither can bacteria perceive dimensions, but they are still controlled by them.

No it does not

A mountain is a part of spacetime. But it does not "exist" for the mountain.

Certainly the mountain is affected by the environment and can be modelled with the spacetime concepts. But the mountain does not perceive anything, and therefore cannot compute isExist (spacetime)

Your talking poetically, or metaphorically, not scientifically I assume?

I'd say philosophically, which is the root of science. The observation, while perhaps may not be provable, makes perfect sense to start a series of long and interesting discussions.

At one time yes, but present day most don't consider philosophy a science. https://opinionator.blogs.nytimes.com/2012/04/05/philosophy-...

I'm willing to call bullshit on this. Space and time may be constructs but they are "helpful" constructs in that they model specific forces which apply to both us and the mountain. I perceive the waste of this body over time: the mountain is subject to these same wastes and transformations as this body.

Are you implying that markov chains can't be genuine? :)
