Good thought experiment. I wonder if pulsars similarly arise from that regular cycle of blackhole formation on a bit larger scale. I would expect some physical expansion and contraction to correlate. As for the fabric/whitehole idea, I am in that camp if wormholes are a provably a thing, than hawking radiation over cosmic timescales could cause the eventual death of the singularity. Though if wormholes are provably a thing, then whiteholes would just be the other end. I wonder the black hole object fully evaporates or are there chunks of ancient black holes just floating around.
