Time dilation problem

  1. Jun 2, 2013 #1
    Hello all, I've been having trouble with this problem; can someone please help? The problem is: If a light beam is shot parallel to me, and I'm running at .7c in the same direction of the light, how much time passes in the light's reference frame (point of view) if I experienced (Earth's reference frame) 5 seconds? Thanks!

    There is no "light's reference frame" in special relativity.
