Is there an equation

  1. Oct 9, 2012 #1
    That calculates how mass a behaves as it nears the speed of light?

    Let me rephrase, if we put a speed of light engine inside a school bus. At what speed would the bus top out at? Is there a certain speed that a weight can go? Or can't go faster than?

    If so what is an equation that can explain this.

    as an added note, the mass experience no change in behavior in its own frame; in other words, it rest mass remains fixed. In addition, the proper time of the mass ticks off at it's same fixed, steady, unchanging rate...

    The bus will approach the speed of light asymptotically, never quite reaching reaching c, no matter how much energy is expended.
