Abstract

Classically, black holes are compact objects with perfect semi-permeable horizons: Anything may enter, nothing may leave. We consider an axiomatic approach that applies to any black hole type, including arbitrarily near-extremal black holes, that can unitarily evaporate away completely by any mechanism. We show that a quantum black hole must either have a leaky horizon (allowing quantum information out), or it must look very different from its classical counterpart having an external neighborhood consisting of exotic matter with super-ordinary entropic content (such as an `atmosphere' of microscopic black holes).

Why This Paper Matters
