Universe could be massive hologram, say theoretical physicists

The universe could be a "vast and complex hologram" and our perception of life in 3D may only be an illusion, according to a theory put forward by astrophysicists. The theoretical physicists, who have been investigating irregularities in the cosmic microwave background (the "afterglow" of the Big Bang), say they have found substantial evidence to support the idea of a holographic universe. And the researchers from the University of Southampton, working with colleagues in Canada and Italy, say there is as much evidence for this theory as for traditional explanations for these irregularities. A holographic universe, an idea first suggested in the 1990s, is one where all the information, which makes up our 3D "reality" (plus time) is contained in a 2D surface on its boundaries. Professor Kostas Skenderis, of mathematical sciences at the University of Southampton, said: "Imagine that everything you see, feel and hear in three dimensions (and your perception of time) in fact emanates from a flat two-dimensional field." "The idea is similar to that of ordinary holograms where a three-dimensional image is encoded in a two-dimensional surface, such as in the hologram on a credit card.
