Suppose I'm an observer out in space and 30 km from me there's another observer, who is static with respect to me. Let's say my name is A and the other is B. We're both far far away from all the cosmical objects that might have a gravitational influence on us. We both notice a spaceship flying with a constant speed - it flies past point A then reaches to B in 30 seconds. Since A and B are static with respect to each other, I suppose we perceive time identically. The question is, how much time passed for the guy in the spaceship, and what is the distance between A to B with respect to him? I appreciate all of your answers!
