And what's the argument that in all of these frames, simultaneity of front and back of car is satisfied? TY, AG What could it possibly mean for the car *not to fit* in the car frame! *Have you ever tried to park a car? Use your brains and you'll figure it out. It's called the Lorentz Parking Paradox. You're trying to park a car of known rest length, in a garage of known rest length. Follow me so far? Now get the car moving and from the car's frame notice how the garage length Lorentz contracts. Follow me so far? At some v or greater, the length of the garage will be smaller than the car's rest length. When this happens most sane individuals will conclude that the car won't fit. OTOH, from the garage frame, the car's length is Lorentz contracted, so most sane individuals will conclude the car WILL fit in the garage. Thus, an apparent paradox, or shall we say a discrency of whether or not, the car can fit in garage, and from the pov of which frame? Final question: are you a sane individual? These questions might be totally ill-posed. If so, with your immensely superior intellect, I'm confident you'll be able to show us how; and if so, THAT WILL BE THE SOLUTION! AG* I don't even know that "the solution" means. *It means what I wrote above. Which frame, if any, can the car be fully contained within the garage? AG * What was the problem to be solved; *Read what I wrote, and better yet what other professionals write about this apparent paradox. AG* How to educate Alan? Simultaneity is a relation between EVENTS, not car parts. *I know that. Now tell me something I don't know. (Who said anything about car parts?)
