no, that is what da has been telling me, and i keep repeating that light has only one speed. the thing is that it still appears to the faster traveler to be going away from him at light speed due to time dialation.
here is the thing though. if you can measure light going in any direction and it is close to the same speed, then your not moving much. if we measure the speed of light comeing from stars the difference in the speed is extreamly small (so small they cant be certain its not the measureing equipment). that is because our planet does not move at anywhere near a measureable fraction of light.
on the other hand if you in a space ship you should be able to detect some difference in the speed of light comeing from infront of you and that comeing from behind you, even with the time dialation. that would tell you what your speed is in relationship to light, and therefore to the universe.
