I'm hardly an expert on relativity, but (as I understand it), mass increases as velocity approaches the speed of light. According to Einstein's equations, mass becomes infinite (at least, the equations show mass divided by zero, a mathematical no-no, at the speed of light). Consequently, no material object can attain the speed of light, much less exceed it. Light itself, of course, has no mass (although that may be open to question; I believe that it is possible that photons have a small mass).

If there are any physicists out there, let's here from them!
