Re: Study reveals substantial evidence of holographic universe

I've recently been thinking on how our human definition of intelligence might relate to holographic principles, particularly in regards to information theory.

We are small creatures, but our networks -- our brains and societies -- represent the most complex information-encoding geometries we've yet seen in the universe.

And I see the way that our curiosity reaches upward in scale, documenting the far corners and folds of the universe; and deeper, interrogating the tiny subatomic spaces; and forward and back, building models of the future and past of this point in time.

And we capture this knowledge and bring it into our tiny space, information encoded in structures along the skin of this rock floating in space.

And I wonder if that's not holographic in some way: That insatiable drive to compress information from massive scales of space and time into the tiniest of spaces...

But of course, this is just armchair philosophizing ;)

You cannot code a particle simulator that perfectly mimics 3D space despite each particle only having two spatial location variables.

We all have that new agey friend on FB who will inevitably share this nonsense. Do we really need to be dealing with it on HN? What's next, Minion memes?

Question, from someone who does not understand the Holographic universe idea: If 'true', is the holographic universe 'merely' a mathematical tool that helps us solve problems, or is it a description of an objective reality, and the universe is 'really' a 2D surface, and our 3D perception is somehow illusory? I understand this is partly a philosophy of science question, but would be interested to hear an expert opinio…

All models are wrong. If a model is not wrong; it is called reality. http://stats.stackexchange.com/questions/57407/what-is-the-m...

This is the right answerer. It pains me that we humans, in our arrogance, do not keep this idea at the forefront of our minds and discussions. I believe far fewer mistakes would be made in science if we more readily accepted our limitations rather than being constantly so enthralled by our own apparent genius. It's not amazing that we amaze ourselves.

To me, saying that model or a theory is wrong is like saying a hammer is wrong. A tool cannot be right/wrong or true/false. However it can be unsuitable for a task. In this case, the task is understanding reality.

It is the second part of the quote (follow the link above): "all models are wrong. Some are useful" -- you are talking about the suitability/usefulness of a model.

The abstract of the paper about which the article reports is less dramatic:

https://arxiv.org/abs/1607.04878

"By comparing the Bayesian evidence for the models, we find that ΛCDM does a better job globally, while the holographic models provide a (marginally) better fit to data without very low multipoles."

So the non-holographic model seems to be better globally even according to the paper.

https://en.wikipedia.org/wiki/Lambda-CDM_model

If the further research proves that holographic models are better, it's good too, let the best wins. But at the moment it still looks to be too early to conclude too much.

While not conclusive, does this not sound like support for what could be Intelligent Design - ID? 'Patterns imprinted in it carry information about the very early Universe and seed the development of structures of stars and galaxies in the late time Universe.' [From the Bulletin] If the universe is encoded on a 2d surface and has been projected on 3d, doesn't that sound like some design/intentional purpose encoded on…

You can always inject god into the unknown. That's what history has shown us over and over and as we slowly uncover how things work there are fewer places to put god into. I see no difference here.

It's crazy to think we are the universe observing and trying to understand itself. Matter organised in a certain way is able to observe itself? How weird is that!

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

It's interesting that to a layman this seems like almost the exact opposite of what string theory proposes dimensionally. Holographic universe theory is stating there are effectively less dimensions, while string theory shows there could be significantly more.

I thought that in order for a holographic universe to exist, then the universe needs to have a non-flat e.g. slightly-curved spacetime; in order to "close the boundary", so to speak.

But my understanding is that so far all our evidence shows that spacetime is flat?

i.e. we spacetime needs to be an Anti-de Sitter space. https://en.wikipedia.org/wiki/Anti-de_Sitter_space But I didn't think many actually think we live in an ADS universe?

Also relevant to string theory, https://en.wikipedia.org/wiki/AdS/CFT_correspondence
