AG * *In this thought experiment I think even you would agree that no matter how fast or slow the car is going there will always be times when the front of the car is in the garage, and times when the back of the car is in the garage; so the question of the day is " Is there any frame of reference in which those two events occur SIMULTANEOUSLY?" Einstein's answer is "yes", provided the car is moving fast enough. And as proof that Einstein's answer was correct, in this thought experiment, above a certain speed, there is NO frame of reference in which there is a car shaped hole in the back door of the garage. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* No. Above a certain speed, since the car is length contracted from the pov of the garage frame, the car will fit in the garage, and waiting some time, then being in a different reference frame, it could hit the back door.
