The Story of Collapsing Stars: Black Holes, Naked Singularities, and the Cosmic Play of Quantum Gravity

Pankaj S. Joshi

Abstract

The most fascinating phenomena in the Universe, black holes and spacetime singularities, occur at the end of a massive star’s life cycle when it has exhausted its internal nuclear fuel and collapses under its own gravity. A star that was millions of kilometers in size shrinks to a pinprick smaller than the dot on an ‘i’. According to Einstein gravity, a collapsing massive star must give rise to a spacetime singularity, which is an extreme region where densities, temperatures, and other physical quantities take arbitrarily large values. The singularity either is covered within an event horizon, ... More
