Coming from a very pure math background, I see why traveling at or faster than light screws up all the math formulas, but physically why can't an object travel at (or faster) than light? What fundamental law of the universe could you be breaking? Thanks.

Thanks for the post, Fredrik. And thanks for the paper: I'll check it out. I am new to this forum (I just registered couple hours ago!) I mainly have a pure math background, and only just starting into mathematical physics. Are you a grad student or professor? At my school there is hardly...

Here is a very general answer: From the axioms of QM and the math that is used to build observables and states of systems, it turns out that position and velocity (and also momentum, because momentum p = mv) are what are called "canonical conjugates", and they cannot be both be "sharply...
