Naked Singularities, Cosmic Time Machines and Impulsive Events

TL;DR

This paper explores the theoretical possibility that naked singularities and cosmic time machines, arising from gravitational collapse, could be responsible for high-energy impulsive astrophysical events.

Contribution

It provides a detailed analysis of how cosmic time machines associated with naked singularities might generate impulsive phenomena.

Findings

Naked singularities can lead to causally ill-behaved space-times.

Cosmic time machines may produce high-energy impulsive events.

Theoretical link between gravitational collapse and energetic astrophysical phenomena.

Abstract

Continued gravitational collapse gives rise to curvature singularities. If a curvature singularity is globally naked then the space-time may be causally future ill-behaved admitting closed time-like or null curves which extend to asymptotic distances and generate a Cosmic Time Machine (de Felice (1995) Lecture Notes in Physics 455, 99). The conjecture that Cosmic Time Machines give rise to high energy impulsive events is here considered in more details.
