Another problem with this scenario is that time slows as the event horizon is approached, so nothing ever actually makes it into a black hole, at least nothing that wasn't there already when it formed. (Assuming that time actually stands still at the event horizon). Regards, Robin van Spaandonk local asymmetry = temporary success
