Unsettling physics in the quantum-corrected Schwarzschild black hole

TL;DR

This paper explores the unusual physics of a quantum-corrected Schwarzschild black hole from Loop Quantum Gravity, revealing confinement of particles and infinite redshift for photons due to negative quantum energy effects.

Contribution

It provides a detailed analysis of geodesics in the quantum-corrected black hole, highlighting novel effects caused by quantum corrections not seen in classical solutions.

Findings

Massive particles are confined radially outward.

Photons can escape to infinity with infinite redshift.

Quantum corrections induce repulsive effects near the horizon.

Abstract

We study a quantum-corrected Schwarzschild black hole proposed recently in Loop Quantum Gravity. Prompted by the fact that corrections to the innermost stable circular orbit of Schwarzschild diverge, we investigate timelike and null radial geodesics. Massive particles moving radially outwards are confined, while photons make it to infinity with infinite redshift. This unsettling physics, which deviates radically from both Schwarzschild (near the horizon) and Minkowski (at infinity) is due to repulsion by the negative quantum energy density that makes the quasilocal mass vanish as one approaches spatial infinity.
