Re: Theory?
Since the incompleteness could very well be in the quantum theory, that is not very strong evidence that GR is either wrong or incomplete. On the other hand, it is known that QM does not predict that gold preferentially absorbs blue light due to the 5d-6s transition distance and so appears yellow, thus we have the field of relativistic quantum chemistry. And then there's gravity... No, I would think relativity has demonstrated more incompleteness in QM than vice versa.
