This feels like it's rearranging the deck chairs on the Titanic. We know GR is incorrect - after all it predicts singularities. GR is also silent on how stress/energy/momentum causes curvature in space time. In that vein, GR seems more like a law of gravity rather than a theory of gravity.

I would suggest we work on an actual theory of gravity before we tackle black hole event horizons and their formation. Such a theory should provide a lot of insight into the formation (or not) of black holes.

By Jove, I think he's got it.

tl;dr: physicists incl. hawking worry about singularities and event horizons, but to us, external observers, these need infinite time to actually form. basically, stop worrying about objects that can't actually exist in our light cone.
