No theory of physics is ultimately "right' in every circumstance. All of them, including relativity theory and quantum mechanics are but approximations, so that regardless of the outcomes in CERN, both have already proven their practical worth. Both, for example, "repudiate" Newtonian physics, but that doesn't mean that Newtonian physics is "void" and "has no value".
Personaly, I think relativity theory is too oversimplified. Quantum theory in fact demonstrates that relativity theory is incomplete.
