Twins Variation [Mentor's note: I split this off from the "twins paradox confusion" thread where it was originally posted because that thread is pretty long already and this is not a continuation of the scenario being discussed there. It would be confusing if M1keh comes back to the other thread and we end up discussing both his scenario and yours simultaneously!] ================================================== I wonder if someone might be able to offer an explanation of the following somewhat related twins paradox I just thought up. I've attached a crude drawing to better explain it. Twin's names are A and B. A and B travel @ .9c in a straight line, A following B, away from Earth. A shoots a laser at B. A sees the laser slowly catching up to B but B turns before it hits arriving safetly back at Earth. B sees the laser traveling towards him @ c, crashing into him before he makes the turn and killing him. Can A and B go for coffee?
