One things that puzzles me is the speed of light. We measure it always the same speed independently if we are moving or still. But here is where i get really confused: if we are moving against a light ray (imagine that I will "bump" with the light ray), the speed that we measure is the same if we are moving in an oposite direction (light moves one direction while I move the oposite direction but moving away)?

Second doubt: Is the slowing of satelites clocks in relation to the Earth clocks the proof (or at least on of the proofs) of the constant of the light speed? I don´t get it. Its to confusing to me.

Thank you
