Black Hole Information  What's the Problem? Speaker(s): Sabine Hossenfelder
Abstract: I will classify the options to solve the black hole information loss problem by how radical a departure from semiclassical gravity they require outside the quantum gravitational regime. I will argue that the most plausible and conservative conclusion is that the problem of information loss originates in the presence of the singularity and that thus effort should be focused on understanding its avoidance. A consequence of accepting the accuracy of the semiclassical approximation is the surface interpretation of black hole entropy. I will summarize the arguments that have been raised for and against such scenarios. Reference: http://arxiv.org/abs/0901.3156
