Building Regular Black Holes

Regular, singularity-free black holes have been studied for more than sixty years as a possible resolution of the black hole singularity problem. Progress, however, has largely been focused on questions at the kinematical or phenomenological level, since no robust dynamical mechanism for their formation has yet been established. This is a central issue, as the viability of regular black holes ultimately depends on such dynamical considerations.

In this talk, I will argue that, if regular black holes play a role in resolving spacetime singularities, they may arise naturally 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.
