Black holes are not the only theory which fits the evidence we have. Simply add 2M to the first 2 r's in the Schwarzschild metric (the equation used to confirm black holes), and you get a metric that fits all the evidence but doesn't predict black holes, hence doesn't raise the black hole information loss paradox, and so isn't incompatible with quantum mechanics that way. That's well known in the cosmological community, but ignored.

We have evidence of luminous matter falling into a black hole and disappearing. What more do you want? What possible other non-black-hole theory fits that evidence?

[benwan]

An "almost black hole" also predicted by Einstein's theory predicts the same observation, as an effect of gravitational time dilation. The non-black-hole theory that fits the evidence is the tweak you replied to. As I said, it fits all the evidence.
