Content: The theory of relativity consist of complex mathematical equations relying on several hypotheses. For example, at Hofstra University general relativity is taught as part of an upperclass math course on differential geometry, based on three stated assumptions. Special relativity assumes that all observers in inertial frames of reference will measure the same value for the speed of light, c and that all inertial frames of reference are equivalent. These hypotheses that can never be fully tested. Relativity rejects Newton's action at a distance, which is basic to Newtonian gravity and also found to be a consequence of quantum mechanics. The mathematics of relativity assume no exceptions, yet in the time period immediately following the origin of the universe the relativity equations could not possibly have been valid, since quantum effects would not be negligible (in the same way non-relativistic quantum mechanics is not valid when dealing with particles traveling near the speed of light). The "continuous" nature of space and time postulated by relativity is in conflict with the "discrete" nature in quantum mechanics, and although theories like string theory and quantum field theory have attempted to unify relativity and quantum mechanics, neither has been entirely successful or proven. Unlike Newtonian physics, in which space and time intervals are each invariant as seen by all observers, in SR the only invariant quantity is a quadratic combination of space and time intervals ( x2 - c2 t2 ). The instantaneous transmission of Newtonian gravitational effects also contradicts relativity. In quantum mechanics, the uncertainty principle suggests that virtual particles can sometimes travel faster than the speed of light which would violate causality, but " [t]he only known way to resolve this tension involves introducing the idea of antiparticles."
