Depletion of energy from Naked Singular regions during gravitational collapse

TL;DR

This paper investigates whether energy can physically escape from naked singular regions during gravitational collapse, showing that in certain models, energy can indeed be transported to observers, with implications for relativity.

Contribution

It demonstrates that energy can escape from naked singularities in gravitational collapse scenarios, using models with null dust and dust to illustrate the process.

Findings

Energy can be transported from naked singularities to observers.

Outgoing null geodesics can be immersed between Vaidya spacetimes.

Similar energy escape considerations apply to dust collapse models.

Abstract

A distinguishable and observable physical property of Naked Singular Regions of the spacetime formed during a gravitational collapse has important implications for both experimental and theoretical relativity. We examine here whether energy can escape physically from naked singular regions to reach either a local or a distant observer within the framework of general relativity. We find that in case of imploding null dust collapse scenarios field outgoing singular null geodesics including the cauchy horizon can be immersed between two Vaidya spacetimes as null boundary layers with non vanishing positive energy density. Thus energy can transported from the naked singularity to either a local or a distant observer. And example illustrating that similar considerations can be applied to dust models is given.
