[quote]When you move faster than light, you have infinite mass.[/quote] wat Anyway, your momentum (mass * velocity), aka "quantity of movement" would be pretty spectacular, so yes, it would indeed -blam!- shit up (because you're, well, a fat man). Why is my "-blam!-" censored and the OP's not?

  • Why?

  • It's just what I heard, and being the extremely scientific man that I am, I have deemed it just plausible enough to be correct. In other words, God knows, but apparently it's true.

  • Your mass increases as you approach the speed of light. The faster you move, the heavier you are. Reaching light speed would cause whatever piece of matter that's moving to have infinite mass, which is something you want to avoid.

  • You don't "want to avoid" anything, because it's never going to happen. You can't have infinite mass. My point is, M = m0/sqrt(1 - (v/c)^2) is not defined for v = c.

  • But you can consider that when v -> c, m -> ∞. You end up dividing the rest mass with an infinitesimally small number and hence get an infinitely large number as a result. You just have no amount of energy that can get you to such speeds.

  • Yes, I'm aware you can't have infinite mass. That's part of the reason you can't travel faster than light.
