Cauchy horizon stability and cosmic censorship

TL;DR

This paper explores how spacelike matter shells can lead to Cauchy horizon traversal and potential violations of cosmic censorship, challenging assumptions about energy conditions and spacetime stability.

Contribution

It demonstrates that the weak energy condition alone does not ensure the validity of the strong cosmic censorship conjecture.

Findings

Spacelike matter shells can enable travel through Cauchy horizons.

Violations of strong cosmic censorship are possible under certain conditions.

Weak energy condition does not guarantee cosmic censorship.

Abstract

Some interesting consequences of spacelike matter shells are presented, in particular the possibility of travelling through Cauchy horizons and violating the strong cosmic censorship principle. These show that the weak energy condition does not guarentee cosmic censorship.
