And if simultaneity is ultimately affirmed, will ALL other frames have the time order reversed? TY, AG C'mon Alan stop playing dumb. It's obvious that driving a car thru at any speed (except "reverse") has the front and back of the car pass through front of garage in that order (and also pass thru the back of the garage in that order); it's a fact that arises because the front of the car precedes the back of the car down the road. *Actually, you're the one who's playing dumb. Or maybe you are dumb. Or maybe you have poor command of English. Suggest you read what you wrote, CAREFULLY! You claimed, and Jesse affirmed, that even when the car fits in the garage, and the ends are measured as simultaneous, there are frames where the two end events (front and back) are simultaneous, and frames where they are not simultaneous. * But in *every* frame the front of the car passes thru the front the garage before the rear; so ultimately affirming that means nothing except the car is going forward, not in reverse. But you couldn't think a moment and figure that out. Instead you rush to your keyboard to write so more questions. Brent This is pure shit. Why did Jesse understand what I meant, but it goes totally over your head? You wrote that events simulaneous in one frame can have their time order reversed in another frame. I took this as a general statement, not necessarily referring just to cars. If you meant something different, learn to write clearly. FU, AG In my other response to you I was talking about the order of the events of the back of the car passing through the front of the garage, compared to the front of the car reaching the *back* of the garage--those events have a space-like separation in Brent's numerical example, so they can occur in different orders in different frames. But in the statement Brent was responding to, you said "So if front and back of car pass through front of garage in that order"--that would seem to mean the event of the front of the car passing through the front of the garage, and the back of the car *also* passing through the front of the garage, is that what you meant or did you miswrite it? The events of the front vs. back of the car both passing the front of the garage have a time-like separation, so all frames will agree on the order of those two events. Jesse I don't recall exactly what I wrote. I might go back to re-fresh my memory. But I can say for sure that something Brent wrote stated that simultaneous events in one frame, can have their time order reversed in some other frame. I asked him to explain how this can be, and apparently, based on what you wrote above, he was mistaken or possibly not writing clearly. AG *So, it is logical to infer from your statement that there could be two events in some frame, that might or might not be simultaneous, in the absense of fitting. Physicists are not expected to be masters of language, but your understanding of your own words doesn't meet grade school level.
