Title: Microstates for non-extremal black holes


Black holes in GR face us with challenging problems such as a spacetime singularity, black hole entropy and the information paradox. In this talk I will go into the proposed resolution in string theory, Mathur's fuzzball conjecture. It entails that there are plenty of 'microstate geometries' that have no horizon themselves, but are very similar to the black hole geometry outside its horizon. Thus far, this proposal has proven most successful for supersymmetric (and hence unrealistic) black holes. I will discuss new work on the construction of non-supersymmetric microstate geometries, and how this could resolve the singularity of non-extremal black holes.
