Do stars die too long? |

Abstract |
Current proposals for regularizing the classical singularity of black holes present long-lived trapping horizons, with enormous inaccessible evaporation lifetimes. We propose an alternative regularization model, inspired in condensed matter gravitational analogs, in which the collapse of a stellar object would result in a genuine time-symmetric bounce. In geometrical terms this amounts to the connection of a black-hole geometry with a white-hole geometry in a regular manner. The complete bouncing geometry is a solution of standard classical general relativity everywhere except in a transient region that necessarily extends beyond the gravitational radius. The duration of the bounce as seen by external observers is very brief. This motivates the search for new forms of stellar equilibrium. |
