Holographic principle Definition and 57 Threads

Reference: http://en.wikipedia.org/wiki/Holographic_Principle The principle states that the description of a volume of space should be thought of as encoded on a boundary to the region, preferably a light-like boundary like a gravitational horizon. For a black hole, the principle states that...

Hello, I am doing a research paper for a final and I chose the holographic principle as my topic. Does anyone have any good sources, or information pertaining to this? Any help is greatly appreciated, thank you. P.S.- I have looked at some of the first links on google, and wikipedia

The holographic principle claims that physics on the surface of a sphere determines the physics inside the volume enclosed by that sphere. And in particular, the entropy calculated from the surface of the sphere limits the entropy inside the sphere. If so, then entropy per unit volume would go...

If the entropy, S of a black hole is proportional to the area of the horizon, A, then, what about an observer moving with a constant velocity, v with the BH? Another observer moving with a constant acceleration with respect to the BH? After all, entropy is an invariant but area is not. So...

I've finished reading Brian Greene's "Fabric of the Cosmos" and the last chapter intrigued me. He talks about how Hawking et al have proven that the maximum entropy inside a black hole is a function of the surface area of the BH, not the volume. This can be expanded to any volume of space...

Hi there.. If was wondering about the relation between information and entropy, in the following context. The way I understand Gerard 't Hoofd's holographic principle is this. We know that the entropy of a black hole is A/4. Now suppose that a volume V was found to have an excess in entropy...

Can anyone give me a basic definition of what the "Holographic Principle" is, exactly? Or care to discuss the idea at all? Thanks.
