Fuzzy-novae

TL;DR

This paper introduces a quantum gravitational collapse model based on loop quantum gravity that prevents singularities and predicts a stable, matter-ejecting phenomenon called a fuzzy-nova, potentially resolving black hole information loss.

Contribution

The model uniquely incorporates local quantum effects to resolve singularities and predicts a fuzzy-nova event, advancing understanding of black hole end states.

Findings

Resolves central and shell-crossing singularities.

Predicts formation of a stable outgoing matter wave.

Suggests a mechanism for black hole mass ejection.

Abstract

We propose a novel phenomenological model of quantum gravitational collapse inspired by loop quantum gravity that ensures a completely regular spacetime evolution. By incorporating quantum gravitational modifications based on local rather than average energy density, our model simultaneously resolves both the central singularity and the shell-crossing singularities. Numerical simulations reveal that the interplay between local quantum repulsion and gravitational attraction leads to the formation of a stable, outgoing solitary matter wave, supported by a dynamical local anti-trapped region. This mechanism allows for a time-like ejection of the entire stellar mass -- a \emph{fuzzy-nova} -- which signals the end of macroscopic black holes. By providing a concrete dynamical mechanism for matter to escape the trapped region, our work sets a new stage for resolving the information paradox and opens a realistic observational window into quantum gravity.
