It investigates black hole properties and spacetime structure in a novel quantum gravity model with broken symmetries, extending previous theoretical work.

Findings

Analysis of singularities in the broken symmetry context

Insights into black hole formation via gravitational collapse

Implications for the global structure of spacetime

Abstract

Since Stephen Hawking discovered that black holes emit thermal radiation, black holes have become the theoretical laboratories for testing our ideas on quantum gravity. This dissertation is devoted to the study of singularities, the formation of black holes by gravitational collapse and the global structure of spacetime. All our investigations are in the context of a recently proposed approach to quantum gravity, which breaks Lorentz and diffeomorphism symmetries at very high energies.
