Closed universes with black holes but no event horizons as a solution to the black hole information problem
Abstract
We show that it is possible for the information paradox in black hole evaporation to be resolved classically. Using standard junction conditions, we attach the general closed spherically symmetric dust metric to a space-time satisfying all standard energy conditions but with a single point future c-boundary. The resulting Omega Point space-time, which has NO event horizons, nevertheless has black hole type trapped surfaces and hence black holes. However, since there are no event horizons, information eventually escapes from the black holes. We show that a scalar quintessence field with an appropriate exponential potential near the final singularity would give rise to an Omega Point final singularity.
