The universe might be a hologram
 

For a while now number crunching physicists have been working on a theory that everything around us is just a hologram.

Now, two papers posted on the arXiv repository, Yoshifumi Hyakutake of Ibaraki University in Japan and his colleagues now provide, compelling evidence that the theory might be true.

In 1997, theoretical physicist Juan Maldacena came up with a model of the universe in which gravity arises from infinitesimally thin, vibrating strings and could be reinterpreted in terms of well-established physics. As you do.

He thought that a mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram. Anything that was really happening took place in a flatter cosmos where there was no gravity and was projected onto this space where we see it all as being reality. It solved apparent inconsistencies between quantum physics and Einstein's theory of gravity. The problem is that it is difficult to prove.

Hyakutake looked at the internal energy of a black hole, the position of its event horizon, its entropy and other properties based on the predictions of string theory as well as the effects of so-called virtual particles that continuously pop into and out of existence.
