How does the universe (laws of gen. relativity, physics) know which of two objects traveling thru space is going faster. using the old rocket cliche: a clock in a rocket traveling, say, .95 speed of light vis-a-vis earth. how does universe know it is the rocket clock to slow down an not the earth's, seems to me there is no way to NOT say the earth is going .95 C and the rocket is "standing still". Assume rocket is not accerlerating (nor earth) but at constant speed.
