Information in the Holographic Universe

-->Theoretical results about black holes suggest that the universe could be like a gigantic hologram

Our innate perception that the world is three-dimensional could be an extraordinary illusion.

An astonishing theory called the holographic principle holds that the universe is like a hologram: just as a trick of light allows a fully three-dimensional image to be recorded on a flat piece of
film, our seemingly three-dimensional universe could be completely equivalent to alternative quantum fields and physical laws"painted" on a distant, vast surface.

The physics of black holes--immensely dense concentrations of mass--provides a hint that the principle might be true. Studies of black holes show that, although it defies common sense, the
maximum entropy or information content of any region of space is defined not by its volume but by its surface area.

Holography may be a guide to a better theory. What is the fundamental theory like? The chain of reasoning involving holography suggests to some, notably Lee Smolin of the Perimeter Institute
for Theoretical Physics in Waterloo, that such a final theory must be concerned not with fields, not even with spacetime, but rather with information exchange among physical processes. If so,
the vision of information as the stuff the world is made of will have found a worthy embodiment.
