Minguzzi, Ettore 2020-03-09T10:58:28Z 2020-03-09T10:58:28Z 2020-03-09 https://hdl.handle.net/10630/19373 The global hyperbolicity assumption present in gravitational collapse singularity theorems is in tension with the quantum mechanical phenomenon of black hole evaporation. In this work I show that the causality conditions in Penrose's theorem can be almost completely removed. As a result, it is possible to infer the formation of spacetime singularities even in absence of predictability and hence compatibly with quatum field theory and black hole evaporation. eng open access Singularidades (Matemáticas) A gravitational collapse singularity theorem that improves Penrose's conference output
