White holes have been long thought of as mathematical curiosities: solutions of the Einstein field equations that cannot be nevertheless dynamically produced in physical processes involving realistic matter. However, quantum gravity may supply the necessary spark to produce them in events that are ubiquitous in the universe, namely in the gravitational collapse of massive stars. In this scenario, the first corrections to general relativity at very short distances lead to repulsive forces that prevent the formation of singularities. These repulsive forces restore the symmetry under time reversal, resulting in quasi-periodic oscillations of the collapsing star that involve transient phases resembling black holes and white holes. This proposal would solve a number of open issues, such as the singularity problem or the information loss conundrum, providing moreover a falsifiable alternative. View this paper
