Our Universe May Be a Giant Hologram

QUOTE Think of any region of space, such as the room in which you’re reading. Imagine that whatever happens in the region amounts to information processing—information regarding how things are right now is transformed by the laws of physics into information regarding how they will be in a second or a minute or an hour. Since the physical processes we witness, as well as those by which we’re governed, seemingly take place within the region, it’s natural to expect that the information those processes carry is also found within the region. But for black holes, we’ve found that the link between information and surface area goes beyond mere numerical accounting; there’s a concrete sense in which information is stored on their surfaces. Physicists Leonard Susskind and Gerard ’t Hooft stressed that the lesson should be general: Since the information required to describe physical phenomena within any given region of space can be fully encoded by data on a surface that surrounds the region, then there’s reason to think that the surface is where the fundamental physical processes actually happen. Our familiar three-dimensional reality, these bold thinkers suggest, would then be likened to a holographic projection of those distant two-dimensional physical processes.

If this line of reasoning is correct, then there are physical processes taking place on some distant surface that, much as a puppeteer pulls strings, are fully linked to the processes taking place in my fingers, arms, and brain as I type these words at my desk. Our experiences here and that distant reality there would form the most interlocked of parallel worlds. Phenomena in the two—I’ll call them Holographic Parallel Universes—would be so fully joined that their respective evolutions would be as connected as me and my shadow.[/quote]

Seriously I think some of these physicists just say this @#(! for attention. What the $#@!!?

your mom wasnt a hologram last night

well it's quite a shortcut to generalize what happen on the surface of a black hole to our whole known universe ...

Unless I misunderstood completely that thing, the premise is that what's happening inside a black hole (a 3D sphere) is full 'stored' on its surface (a 2D surface) so this can be generalized to our universe (a 3D sphere)... but hey our universe isn't a black hole.

IMHO, the 3D sphere of a black hole can be stored (or "parallelized" in term of parallel universes) to a 2D surface because of special properties inside the black hole. Generalizing this to any 3D volume (including our universe) is quite an unproven step.

and now my head hurts.

I heard about this last year.

It's just a theory.

I challenge you to prove it.

The parallel universe theory is old. It's as old as Dome's mom, who was had by Brood last night.

It's about the ultimate question of life, the universe and everything being projected from a far off point, somewhere in grid 42.

Now imagine that being said in Zoidbergs' voice.

IIRC this holographic universe theory is not only pretty old, but is actually no longer popular -- it seems there's been some evidence involving observations of the cosmic microwave background interstellar gamma rays or something that suggests it isn't true. I can't remember the details however.
