DESC: Stanford physicist Leonard Susskind challenges Stephen Hawking's "information paradox"--the theory that all information and matter that falls into a black hole is irrevocably lost--with a controversial "holographic theory" that claims that black holes store the information of everything that enters them on their event horizon. Even more shocking, Susskind contends that reality itself may be merely a kind of holographic projection of this vanished information, and that our known universe is actually a representation of matter that has already fallen into a black hole.
