On physical insignificance of null naked singularities

TL;DR

This paper demonstrates that null naked singularities are physically insignificant because their energy is trapped and unobservable, reinforcing the cosmic censorship hypothesis in a highly general setting.

Contribution

It proves that null naked singularities cannot be observed or have physical significance in the most general collapse scenarios, supporting cosmic censorship.

Findings

Null naked singularities trap all energy, making them unobservable.

The result holds for general matter and spacetime without symmetry assumptions.

Supports the cosmic censorship hypothesis by showing null naked singularities are physically irrelevant.

Abstract

In this work we study collapse of a general matter in a most general spacetime i.e., a spacetime with any matter and without (assuming) any symmetry. We show that the energy is completely trapped inside the null singularity and therefore they cannot be experimentally observed. This most general result implies, there is no physical significance of the null naked singularities irrespective of their existence. This conclusion strongly supports the essence of cosmic censorship hypothesis.
