Disappearance of Black Hole Singularity in Quantum Gravity

TL;DR

This paper demonstrates that applying a Loop Quantum Gravity-inspired quantization to the Schwarzschild black hole interior removes the classical singularity, allowing spacetime to extend beyond it, thus resolving the singularity problem.

Contribution

It introduces a novel application of Husain and Winkler's quantization to black hole interiors, showing singularity disappearance in quantum gravity.

Findings

Black hole singularity is resolved in quantum gravity

Spacetime extends beyond classical singularity

Supports loop quantum gravity approaches

Abstract

We apply techniques recently introduced in quantum cosmology to the Schwarzschild metric inside the horizon and near the black hole singularity at r = 0. In particular, we use the quantization introduced by Husain and Winkler, which is suggested by Loop Quantum Gravity and is based on an alternative to the Schrodinger representation introduced by Halvorson. Using this quantization procedure, we show that the black hole singularity disappears and spacetime can be dynamically extended beyond the classical singularity.
