On the quantum corrected gravitational collapse

TL;DR

This paper models quantum-corrected gravitational collapse, showing that quantum effects prevent the formation of event horizons and singularities, leading to complete evaporation and resolving the information paradox.

Contribution

It introduces a quantum improved model of stellar collapse that avoids traditional singularities and event horizons, providing a new perspective on black hole evaporation.

Findings

Formation of a closed apparent horizon due to quantum effects

Complete evaporation of the collapsing star without forming an event horizon

Resolution of the information paradox without firewalls

Abstract

Based on a previously found general class of quantum improved exact solutions composed of non-interacting (dust) particles, we model the gravitational collapse of stars. As the modeled star collapses a closed apparent 3-horizon is generated due to the consideration of quantum effects. The effect of the subsequent emission of Hawking radiation related to this horizon is taken into consideration. Our computations lead us to argue that a total evaporation could be reached. The inferred global picture of the spacetime corresponding to gravitational collapse is devoid of both event horizons and shell-focusing singularities. As a consequence, there is no information paradox and no need of firewalls.
