I have a problem with relitive motion. If a light source is moving toward me a some high percent of c, the light will not reach me any sooner than if the light were stationary. The intantanious position of the light is the only thing that matters. Light is bound by a maximum propigation rate that is not determined by v. And if I am the one that is moving, position is still the only determining factor. I don't see how to determine the speed exclusive of position. I know this probably sounds dopey, but how does all this work?
