Mass Inflation in Quantum Gravity

TL;DR

This paper investigates mass inflation inside Reissner-Nordström black holes within quantum gravity, finding that quantum effects do not prevent the classical mass inflation phenomenon or the formation of its singularity.

Contribution

It demonstrates that mass inflation persists in quantum gravity, extending classical results to a quantum framework using canonical formalism.

Findings

Mass inflation occurs in quantum gravity similar to classical predictions.

Quantum effects do not prevent the formation of mass inflation singularity.

The classical picture of mass inflation remains valid in quantum gravity.

Abstract

Using the canonical formalism for spherically symmetric black hole inside the apparent horizon we investigate the mass inflation in the Reissner-Nordstr$\ddot o$m black hole in the framework of quantum gravity. It is shown that like in classical gravity the combination of the effects of the influx coming from the past null infinity and the outflux backscattered by the black hole's curvature causes the mass inflation even in quantum gravity. The results indicate that the effects of quantum gravity neither alter the classical picture of the mass inflation nor prevent the formation of the mass inflation singularity.
