black hole complementarity

E725131

proposal in quantum gravity theoretical principle

Black hole complementarity is a theoretical principle in quantum gravity proposing that information falling into a black hole is both reflected at the event horizon and passes through it, with no single observer able to witness any violation of quantum mechanics or general relativity.
