Faster light

  1. Jul 4, 2012 #1
    Hello I'm new to the forums and was wondering,

    Since time is not a constant, and speed is a function of time, would light have a higher speed when time passes by quicker? It seems kind of obvious but I'm not really sure.

    time is constant for you. when we look at someone speeding by we would see that their clock appears to be ticking more slowly. conversely when they look at our clock they conclude that our clock is ticking more slowly.
    (special relativity)

    We would measure their speed using the distance they traveled as measured by us and our clock.

    To us time is a constant. Our ideal clock ticks at the same rate always if at rest (ie not moving) in our frame of reference.
