I repeat, above a certain speed there's NO frame of reference in which a car shaped hole appears on the back door of the garage. * *> why is it claimed that lack of simultaneity between frames solves the > problem, since we're only considering simultaneity in garage frame where > the car fits? AG * *The garage man** says that due to length contraction the car will fit in the garage, and to prove it he says that both doors were closed while simultaneously both the front and the back of the car were in the garage. But the car driver disagrees, he insists the car has not fit in the garage because those two events were **not** simultaneous. Everybody agrees there was a time when the front of the car was in the garage, and everybody agrees there was a time when the back of the car was in the garage, but they disagree if those two events happened at the same time that both doors were closed. * > *> It's crazy you're still on this... wtf is your definition of fits in > which doesn't involve simultaneously having rear and front of the car in > the garage? * *Huh? That is exactly my definition of "fitting", and that's exactly why they disagree if the car has fit. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* ida -- You received this message because you are subscribed to the Google Groups "Everything List" group.
