First the OP was not about relativity (SR + GR + RQFT) but only about General Relativity. Second General Relativity is neither a final theory of gravity nor explain all observed data. And *new* theories can explain *both* the *old* results explained by relativity and the *new* results cannot be explained by relativity. -- http://www.canonicalscience.org/

For example, gravitional waves are prediction of relativity. Since, gravitational waves will never be observed, its non-observation never will contradict relativity! |
