Textbook Question
Chapter S2, Problem 25EAP
Does It Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.
25. If you see someone's time running slowly in a different reference frame, that person must see your time running fast.
