Description
A complete theory of quantum gravity is generally expected to cure the singularities inherent to the mathematical black holes predicted by general relativity. In the absence of such a theory, singularity-free models of so-called regular black holes have become a popular alternative to avoid the nontrivial causal structures typically associated with mathematical black holes. In this talk, we derive a generic condition that spherically symmetric dynamical regular black holes must satisfy to be compatible with the first law of black hole mechanics and investigate the thermodynamic consequences of the singularity resolution. We examine the dynamical generalizations of models typically considered in the literature, and demonstrate that none of them satisfies the necessary condition required to be consistent with the first law.
