Question
Because of time dilation, you observe the hands of your friend's watch to be moving slowly. How does your friend view your watch - as running slowly, nunning rapidly, or neither?
Step 1
Time dilation is a difference in the elapsed time measured by two observers, due to a relative velocity between them or to a difference in gravitational potential between their locations. Show more…

Because of time dilation, you observe the hands of your friend’s watch to be moving slowly. How does your friend view your watch: as running slowly, running rapidly, or neither?
You and your best friend buy identical watches and decide to put time dilation to the test! You are in frame S' traveling with speed v = 0.5c with respect to your friend who is in frame S. When your origins coincide, you both synchronize your watches and both agree to send a light signal to each other after one hour has passed on your watches. When does the observer in S receive the signal from the observer in S'?
You are floating in space when you notice a flying saucer circling you. Each time it passes in front of you, you note the reading on its clock. Do you see its clock advancing faster or slower than your wristwatch? Does the space alien see your wristwatch advancing faster or slower than his clock? Explain.
