View source for Black hole information paradox

The '''black hole information paradox''' is the apparent contradiction between [[quantum mechanics]], which requires that information be conserved, and [[Stephen Hawking]]'s 1974 prediction that [[Hawking radiation]] is purely thermal and carries no information about the matter that fell into the [[black hole]]. If a black hole evaporates completely, the information describing the quantum state of infalling matter seems to be destroyed — a violation of the unitary evolution that underlies all quantum physics. The paradox has driven decades of research in [[quantum gravity]], producing proposals from black hole complementarity to the firewall argument, and remains unresolved. Its resolution will likely require a fundamental revision of how we understand spacetime, information, and the relationship between them.
