I will go over the recent firewall debate. I will argue that unitarity requires every quantum of radiation leaving the black hole to carry information about the initial state. Unitary evaporation is thus inconsistent with an information-free horizon at every step of the evaporation process. To address the experience of an infalling observer, I will argue for fuzzball complementarity. Unlike black hole complementarity and observer complementarity which postulate asymptotic observers experience a hot membrane while infalling ones pass freely through the horizon, fuzzball complementarity postulates that fine-grained operators experience the details of the fuzzball microstate and coarse-grained operators experience the black hole. I will along the way also discuss some other ideas that have come up to address the firewall. |
