I would doubt it, obviously. But that doesn't mean it's utterly impossible. I accept that possibility under the strictest sense of "I don't KNOW, factually, that it is not the case", though obviously it is not likely based on what my current knowledge tells me. The funny thing about knowledge and fact is that they are both pretty fluid. It was FACT for a very long time that the earth was flat, was it not? During that time, few if any scientists argued the point because it was simply known to be true... as true as 1+1=2, and we now know it was not true at all.

E=Mc^2 is a mathematical equation that specifies the conversion of energy into mass (or vice versa).
c in this equation equates to the speed of light, but doesn't proffer proof that nothing can transcend it, or even that
c, being a constant, is truly constant. It is constant in so much as our ability to view it's speed from our perspective... which is part of the "Special Theory of Relativity". People have already been able to slow the speed of light in laboratory settings. That would make it NOT a constant. Also, quantum mechanics could make this more or less true down the road.
Regardless, E=Mc^2 does not prove that nothing can be faster than
c. It's a conversion specification.
