You draw a different map and give it a different label. But it's the same event. It doesn't become two different events because two different brought different clocks to it. If not that, then what? I see this in those spacetime diagrams. If their clocks disagree at the reunion, how do you define "the event"? AG It's the event of Red and Blue meeting again. Brent *You have both accelerating in one of your diagrams, which is NOT how the TP is described, while also claiming there is no acceleration in explaining the TP. Is it any wonder that your presentation is unintelligible? Moreover, in light cone diagrams, the labeled spacetime coordinates are referred to as "events" which are, or not, causally connected. So if I am confused, I suppose I should blame the "experts". AG * -- You received this message because you are subscribed to the Google Groups "Everything List" group.
