"Black rings, microstates, and the information paradox" |

I will review the construction of BPS solutions that describe ""black hole microstates"" - smooth solutions that have the same charges and asymptotics as black holes, but do not have a horizon. I will then discuss some of the properties of these solutions that indicate that they describe typical black hole microstates. If so, string theory would imply that a classical black hole solution is a thermodynamic approximation of an ensemble of horizonless configurations, and that this solution stops giving a valid description of the physics at the scale of the horizon. I will finish by discussing some observational implication of this fact. |
