Collapsing shells of radiation in higher dimensional space-time and the cosmic censorship conjecture

TL;DR

This paper investigates the gravitational collapse of radiation shells in higher-dimensional spacetimes, demonstrating that highly inhomogeneous collapse can produce naked singularities, thus challenging the cosmic censorship conjecture.

Contribution

It provides new insights into how non self-similar collapse in higher dimensions can lead to naked singularities, extending previous understanding of cosmic censorship.

Findings

Naked singularities form in non self-similar collapse.

Highly inhomogeneous collapse violates cosmic censorship.

Self-similar models can be explicitly constructed.

Abstract

Gravitational collapse of radiation shells in a non self-similar higher dimensional spherically symmetric spacetime is studied. Strong curvature naked singularities form for a highly inhomogeneous collapse, violating the cosmic censorship conjecture. As a special case, self similar models can be constructed.
