How do you explain the "twin paradox" to a friend Talking with a friend at work I encountered a problem, "No, he was wrong. There is no way possiable that someone can age at a diffrent rate because they are moving at a diffrent speed." We all know a person that has said this and have spent alot more time than perhaps one would like to get over that initial classical thinking. I would like to know how everyone likes to explain the "twin paradox" to someone who is intrested but is stuck in a world of falling apples and cars that only move at 55mph. Guess my question really is, How do I explain time dialation to a friend who only wishs to discuss it and is not yet interested enough to pick up a book?
