Abbas at Aula.cc exerpts this from Scientific American:

“…our universe, which we perceive to have three spatial dimensions, might instead be ’written’ on a two-dimensional surface, like a hologram. Our everyday perceptions of the world as three-dimensional would then be either a profound illusion or merely one of two alternative ways of viewing reality.”
