Model metrics for quantum black hole evolution: Gravitational collapse, singularity resolution, and transient horizons
Samantha Hergott, Viqar Husain, Saeed Rastgoo
Abstract
It is widely accepted that curvature singularity resolution should be a feature of quantum gravity. We present a class of time-dependent asymptotically flat spherically symmetric metrics that model gravitational collapse in quantum gravity. The metrics capture intuitions associated with the dynamics of singularity resolution, and horizon formation and evaporation following a matter bounce. A parameter in the metric associated with the speed of the bounce determines black hole lifetime as a power of its mass; this includes the Hawking evaporation time ${M}^{3}$.
