| contents | The prediction of spacetime singularities, regions of infinite curvature where classical physics breaks down, is one of the most profound challenges in General Relativity (GR). In particular, black hole solutions such as the Schwarzschild and Kerr metrics feature central singularities that signal the incompleteness of the theory in high curvature regimes. This thesis is devoted to the study of modified theories of gravity that aim to resolve these singularities and construct physically viable models of regular black holes: black holes that retain an event horizon but exhibit no curvature divergence anywhere in the spacetime ... Throughout the thesis, particular care is taken to ensure that the proposed models are physically sensible: they reduce to GR in the appropriate limits and lead to well behaved curvature scalars. Collectively, these results highlight the viability of regular black hole models in modified gravity theories, providing a promising path toward a consistent semiclassical description of black holes that avoids the need for quantum gravitational resolution of singularities. (Full abstract can be found in document). |
