I don't disagree. But if you look at Brent's plots, he shows what I
have been saying; namely, from the car's frame, the car doesn't fit;
and from the garage's frame it does fit (when car is modeled at v =
.8c). So far, so good. BUT if you can imagine a physical experiment
with the same parameters, you will presumably observe only ONE outcome.
Which outcome you observer depends on how you observe it. If you are at
rest relative to the garage and standing at it's midpoint, you will see
the rear of the car enter before you see the front of the car exit. But
if you're at the middle of the car and moving with it, you will see the
front of the car exit before you see the rear of the car enter. This is
simply a consequence of the speed of light being the same in all
inertial frames.

So what happened to the other outcome, apparently falsified? After
all, it is *impossible *to observe both outcomes, since they
*contradict* each other. _THIS_ is the point I have been making all
along. AG
