Description
Scale dependence is a common feature of effective spacetime geometries that emerge from nonperturbative aspects of quantum gravity. In this talk, I will investigate how such scale dependence can substantially modify the conventional properties of Hawking radiation. I consider a framework in which the position and mass of the collapsing matter that forms a black hole depend on the momentum of outgoing probe particles. I will show that this scale dependence can lead to a strong suppression of Hawking radiation after the scrambling time, far earlier than the conventional evaporation timescale. This result points to a qualitatively different picture of black hole evaporation and may provide a new perspective on the black hole information paradox.
