Naked singularities in cylindrical collapse of counter-rotating dust shells

TL;DR

This paper demonstrates that gravitational collapse of cylindrical and prolate shells of null dust can lead to the formation of globally naked singularities, challenging traditional notions of cosmic censorship.

Contribution

It provides explicit solutions showing the formation of naked singularities in cylindrical dust shell collapse, expanding understanding of gravitational collapse scenarios.

Findings

Collapse solutions admit globally naked singularities

Naked singularities occur in cylindrical and prolate dust shell collapse

Challenges cosmic censorship in specific collapse models

Abstract

Solutions describing the gravitational collapse of asymptotically flat cylindrical and prolate shells of (null) dust are shown to admit globally naked singularities.
