While reading one of Starthrower's threads, I became quite confused.
If an object moves at close to c relative to the earth, but without acceleration, how do we know that time slows down for it instead of our planet? An inertial reference frame is point that doesn't accelerate, correct? Both the planet and the object could then be IRFs. Where does time slow down? What gives?
