Has anyone seen this? Holographic Universe discussed in Nature?

#2
Does anyone know if there have been any books on this topic. There are a lot of articles and videos but I'm looking for something a bit more in-depth.

Thanks for sharing the link, btw!

Susskind's - The Blackhole War is a great book which develops his ideas from scratch, and explains them in terms a layman can understand.

Thanks so much everybody for these interesting links.
I remember reading The Holographic Universe some years ago and I found it fascinating.
It's good to see a great idea being backed by others.

Doesn't it seem like David Bohm's theories are getting some traction (without him being mentioned?)
That's because the holographic theory of this article is not the same theory that the holographic theory of Bohm and Pribram: according to the theory of this article, the reality may be a hologram due to a combination that I can not understand between quantum gravity and string theory, which is not the path followed by Bohm and Pribram to reach their approaches; both theories postulate that reality is a hologram, but in ways completely different.

"The Holometer. Sounds like something out of Star Trek, right? Well, the Department of Energy’s Fermi National Accelerator Laboratory is engaging in a pretty interesting experiment that bears the sci-fi name. Its goal? To answer some questions about the universe, including whether or not we live in a hologram.

Characters on a TV are 3D, but they exist on a 2D screen. In the same way, we could be blissfully unaware that our 3D universe is just an illusion. It could very well be that you and me and everything in between, seemingly solid, is nothing more than a hologram. Yikes!

Matter is the result of a frequency, even the matter that makes up you, the chair you’re sitting in, the house you live in, the dog you’re petting; everything. If frequencies are amplified, the structure of matter will change. Equally, if you change anything about the hologram, you can change the entire system.

So what happens when you sit too close to your TV? You’ll probably get a headache, or as your mom probably threatened, you’ll go blind, but you’ll notice something else. You’ll notice pixels. The tiny points of light that make a perfect image if you take a step back. Scientists have begun to think that the universe’s information may be packed up in the same way. But this ‘pixel’ could be 10 trillion trillion times smaller than an atom; what physicists refer to as the Planck scale.

Some theoretical physicists suspect that space-time is pixelated. It’s grainy, in a way. And since a 2D surface can’t store the necessary information to render a 3D object, these pixels would be larger in hologram. “Being in the [holographic] universe is like being in a 3D movie,” says Craig Hogan of Fermilab in Batavia Illinois. “On a large scale, it looks smooth and three dimensional, but if you get close to the screen, you can see that it is flat and pixelated.”

“We want to find out whether spacetime is a quantum system just like matter is,” Hogan continued. “If we see something, it will change the ideas about space we’ve used for thousands of years.”

Woah.

So how is this experiment going to work? We’ll get to that. First, a little background. The Holometer team is made up of 21 students and scientists from Fermilab, Massachusetts Institute of Technology, The University of Michigan, and the University of Chicago. The team includes Hugan and Stephan Meyer; both astronomy and astrophysics professors at UChicago.

The experiment seeks to probe the limits of the universe’s ability to store information. What they call “Holographic noise” is expected to be present in all frequencies, but the scientists’ challenge is not to be fooled by other sourced of vibratiions. The Holometer is testing a frequency of millions of cycles per second, incredibly high, so the motions of normal matter won’t cause any confusion.

“If we find a noise we can’t get rid of, we might be detecting something fundamental about nature–a noise that is intrinsic to spacetime,” said Fermilab physicist Aaron Chou, lead scientist and project manager for the Holometer. “It’s an exciting moment for physics. A positive result will open a whole new avenue of questioning about how space works.”

If this experiment yields a positive result, it would change every assumption we have about the world we live in. It would show that everything is a projection from a flat surface, possibly billions of light years away. Talk about trippy!"
The Holometer experiment, funded by the U.S. Department of Energy and other sources, will gather data over the next year. For more information about the experiment, visit http://holometer.fnal.gov/.

"New Model Suggests The Big Bang Never Happened"

"A new model suggests that there never was any big bang at all. Which isn’t to say that creationist theocratic beliefs are right, still quite the contrary. This new quantum equation suggests that the Universe simply has no beginning or end!
Researchers have made a new model that applies our most updated understanding of quantum mechanics to the theory of general relativity, and according to the results, the Universe may simply have been going on forever.

Current thinking says that the universe is about 13.8 billion years old, and that once upon a time, everything that exists today was crammed into a tiny point – a singularity- that was so dense that we can’t see anything before it. It exploded, thus, big bang.

This model is derived of mathematics of general relativity, but even so, scientists take one major issue with it. It explains only what happened after the big bang, but not before it.

“The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there,” co-creator of the new model, Ahmed Farag Ali from Benha University and the Zewail City of Science and Technology, both in Egypt, told Lisa Zyga from Phys.org.

Ali has resolved this issue by creating a new model of a universe that is infinite; one in which the big bang never actually happened. This model doesn’t predict a “big crunch” either. The “big crunch” theory states that eventually the universe would just come crashing back onto itself.

“In cosmological terms, the scientists explain that the quantum corrections can be thought of as a cosmological constant term (without the need for dark energy) and a radiation term,” says Zyga. “These terms keep the Universe at a finite size, and therefore give it an infinite age. The terms also make predictions that agree closely with current observations of the cosmological constant and density of the Universe.”

This hypothesis states that the universe is filled with what’s called a quantum fluid, which may be filled with gravitons. Gravitons are a hypothetical particle that doesn’t have a mass or force of gravity. This theory is supported by a related paper that shows gravitons can form, at least in theory, a Bose-Einstein condensate at the temperature of the Universe.

A separate hypothesis thinks that the big bang caused two parallel universes to be created, one moving forward in time and the other backward.

Of course, this new model needs to be analysed and analysed again in order for it to be accepted, but if it holds true, it’ll likely change our perception of existence and solve a lot of issues with our current ideas.

“It is satisfying to note that such straightforward corrections can potentially resolve so many issues at once,” Das told Zyga.

The title of the nature article is misleading. The article is about a hypothetical universe that has different dimensions than our universe.

http://www.nature.com/news/simulations-back-up-theory-that-universe-is-a-hologram-1.14328#/b1
Neither of the model universes explored by the Japanese team resembles our own, Maldacena notes. The cosmos with a black hole has ten dimensions, with eight of them forming an eight-dimensional sphere. The lower-dimensional, gravity-free one has but a single dimension, and its menagerie of quantum particles resembles a group of idealized springs, or harmonic oscillators, attached to one another.

Nevertheless, says Maldacena, the numerical proof that these two seemingly disparate worlds are actually identical gives hope that the gravitational properties of our Universe can one day be explained by a simpler cosmos purely in terms of quantum theory.
If our universe didn't have three spatial dimensions, planetary orbits would be unstable and life as we know it would be impossible.
