Presentation

The problem of preserving unitary evolution in the presence of an evaporating black hole remains a key problem in quantum gravity, expected to point to new fundamental principles. It has been argued that unitary evolution implies breakdown of spacetime at the horizon (a “firewall”), or other large near-horizon effects. I explore a basic set of postulates, including a “correspondence...
