Speed of a light spot

  1. Jul 31, 2010 #1
    Please remind me, the red dot caused by a laser pointer, can it go faster than c?

    It's neither matter, nor light, it's a series of distinct reflections, so with a quick flick of my wrist here on earth, that spot could zip accross the moon faster than c right?

    Yes it can - there is no information moving, so no problem
