Gamma-ray bursts as the birth-cries of black holes

TL;DR

This paper proposes that gamma-ray bursts originate from general relativistic effects during massive star collapse, allowing energy escape before black hole formation.

Contribution

It introduces a novel explanation for gamma-ray bursts based on relativistic effects in stellar collapse, differing from previous models.

Findings

Closed trapped surfaces can form late in collapse.

Energy can escape as fireballs before black hole formation.

Relativistic effects could explain gamma-ray burst phenomena.

Abstract

The origin of cosmic gamma-ray bursts remains one of the most intriguing puzzles in astronomy. We suggest that purely general relativistic effects in the collapse of massive stars could account for these bursts. The late formation of closed trapped surfaces can occur naturally, allowing the escape of huge energy from curvature-generated fireballs, before these are hidden within a black hole.
