Lets say that we have a spaship(with a man) that has speed,and a woman at ground that has not speed. Man throughs a light at ground and light comes again at spaceship. For man light follow a straight line,but for woman follow a V destination. Both see light speed to run with the same constant speed.But man see light to follow a smaller destination,so for woman man's clock run slower,but for man woman's clock run slower too. That is clear to me. That what I want to ask is:"Both will count the same time at their clocks. For example If man counts 2 second,what about woman?" Sorry for my bad english. Thanks a lot !!!
