On gravitational spherical collapse without spacetime singularity

TL;DR

This paper explores how quantum effects can cause bounce solutions in gravitational spherical collapse models, potentially avoiding spacetime singularities in both homogeneous and inhomogeneous scenarios.

Contribution

It introduces the concept that quantum effects can induce bounce solutions in spherical collapse, challenging the classical singularity outcome.

Findings

Quantum effects lead to bounce solutions in collapse models

Both homogeneous and inhomogeneous collapse scenarios are considered

Potential avoidance of spacetime singularities is discussed

Abstract

This note discusses possible quantum effects in the context of homogeneous flat FLRW and inhomogeneous LTB gravitational spherical collapse, which lead to bounce solutions.
