No. In mathematics we prove conjectures, theorems, etc. In science we do not prove a hypothesis. We run experiments to either support or refute the hypothesis, but as time goes on and new evidence becomes available conclusions can swing direction. Proof is an exercise pursued by mathematicians.

Yes. Ordinary quantum field theory is as wrong as Newtonian gravity for not including GR effects. That is to say, it is a perfectly fine theory inside its domain of validity, which in this case means pretty much everything below the Planck scale, just as Newtonian mechanics is valid for speed much less than the relativistic scale (the speed of light). ...

Where did you hear it's the only way to include gravity? There is also loop quantum gravity on Wikipedia. But even if we leave this aside, the answer is clearly No As with every theory, we can never be sure it is correct or it is "whats really going on". The only thing we can test is, if the theory gives the same results we see in nature. As long as the ...

Is Bekenstein entropy limit inconsistent with universal continuity? Yes, but that doesn't mean the Bekenstein bound is correct and everything is fine. Entropy can be considered as "sameness", related to available energy. And the expression $S \leq \frac{2 \pi k R E}{\hbar c}$ has a c in it, but the coordinate speed of light at the event horizon is zero. ...
