If we have two balls, a red and blue ball, and the red ball passes the blue ball at 99.9% the speed of light, would "time" for the red ball pass slower than it does for the blue ball? If it does, and if speed is just relative, couldn't we say the blue ball is passing the red ball at 99.9% the speed of light, but just in the opposite direction? Wouldn't this cause the blue ball and red ball to age at exactly the same speed and make "time travel" impossible?
