Description
Regular, singularity-free black holes have been studied for more than sixty years as a possible resolution of the black hole singularity problem. Progress in this direction, however, has been limited by the lack of a robust dynamical mechanism for their formation. I will argue that, if regular black holes are relevant to the ultimate resolution of spacetime singularities, they are most likely to arise from resummed higher-derivative corrections of the kind expected in quantum gravity. I will discuss a recent explicit realization of this idea, survey the main results obtained so far in this framework, and highlight the major open problems that remain.
