Effective Schwarzschild interior, Raychaudhuri equation, and singularity resolution

Saeed Rastgoo (York University, Canada)

RESUMEN: I will discuss how the dynamics of the interior of the Schwarzschild black holes is effectively modified due to loop quantum gravity and show how this leads to singularity resolution and a bounce scenario. I also present our recent work showing how, using the same analysis, the Raychaudhuri equation picks up effective terms that reverse the classical focusing of the geodesics near the singularity and turn it into defocusing.
