For what it's worth, it's not "Nothing can travel faster than the speed of light" so much as "Moving faster than light is a concept which makes no sense physically."

I'm sure this theory will be proven to be not entirely correct someday. As a corollary, I expect that e=mc^2 will also be slightly modified.

I don't know from what background you're making that statement but in general it's good for people to know that E=mc^2 only when the object is at rest, otherwise you must account for momentum. http://en.wikipedia.org/wiki/Mass%E2%80%93energy_equivalence...
