Why Can't Anything Travel Faster than Light?

[Rhondazvous]

btw it's not customary any more to call it relativistic mass, usually people simply talk about the energy of the moving object E, and instead of "relativistic mass", it's just E/c^2

(putting on ye old thinking cap)

So if e = m then they will always be equal and never enough e to make v > c. As to why c is the magic number, vorlon has the best answer.

Possible tie in: Only gamma rays have enough energy to transform energy into matter, and that matter is quickly transformed back into energy when the electron/positron pairs collide, so as v approached c and produces e which is transformed back into m the energy lost in this transformation slows it down.

Practical application: You weigh more when you exercise (move) so to lose weight, stand still..
