The Structure of Naked Singularity in Self-similar Gravitational Collapse II

TL;DR

This paper extends previous work to show that strong curvature naked singularities can form in self-similar gravitational collapse involving any matter satisfying the weak energy condition, challenging traditional views on singularity visibility.

Contribution

It generalizes earlier results to demonstrate the occurrence of naked singularities in a broader class of self-similar collapse models under the weak energy condition.

Findings

Strong curvature naked singularities can occur in self-similar collapse

The results apply to any matter satisfying the weak energy condition

Challenges the notion that singularities are always hidden behind horizons

Abstract

Generalizing the results of Joshi and Dwivedi in Commun.Math.Phys. 146, p.333 (1992), it is pointed out that strong curvature naked singularities could occur in the self-similar gravitational collapse of any form of matter satisfying the weak energy condition for the positivity of mass-energy density.
