A comment on a fine-grained description of evaporating black holes with baby universes
Abstract We study a partially fine-grained description of an evaporating black hole by introducing an open baby universe with a boundary. Since the Page’s calculation of the entropy of Hawking radiation involves an ensemble average over a class of states, one can formally obtain a fine-grained state...
