Findings

Describes a non-singular, spherically symmetric metric with black hole and white hole regions.

Models gravitational collapse with matter bounce avoiding singularities.

Offers a framework for quantum gravity phenomenology.

Abstract

We present an asymptotically flat spherically symmetric non-singular metric that describes gravitational collapse and matter bounce with transient black hole and white hole regions. The metric provides a dynamical counterpart to proposed static non-singular black holes, and a phenomenological model for possible black hole to white hole transitions in quantum gravity.
