In classical gravity, nothing can escape from a black hole, not even light.In particular, this happens for stationary black holes because their horizons are null.We show, on the other hand, that the apparent horizon and the region near r = 0 of an evaporating charged, rotating black hole are both timelike.This implies that there exists a channel, via which classical or quantum information can escape to the outside, as the black hole evaporates.Since astrophysical black holes have at least some rotation, our results apply to all black holes in nature.We discuss implications of our result.
