Yes, you look at it just in terms of lengths, which

We seem to be on the same page concerning use of length
contraction to explain the
differing results in the frames under consideration. But I
remain unclear how the
disagreement of simultaneity can also give the same results.
For example, suppose
from the pov of the garage frame, the car fits in the garage
for sufficient v, with room
to spare, but the front and rear end EVENTS do not Lorentz
transform into simultaneous
events in the car frame. Can't there be other ways for the
car to fit, using another set
of events which*are* simultaneous in the car frame? AG
Sure. If the car's speed was just right, it would be the
same length as the garage. Then in the diagram A and B would
be at the same time in the garage frame the car would be just
the right length such that the rear of the car entered the
garage just as the front exited the garage. Since we know
the car is 12 long and the garage is 10 long we can calculate
the required speed from 10/12 =sqrt{1-v^2} which yields
v=0.553 if I did the arithmetic right.
That would be 0.553c. So, if the front and back events in the
garage frame are simultaneous in the car frame AND in the garage
frame,
Nobody said that the events were simultaneous in the car frame.
The car is contracted in the car frame. You keep throwing shit in
problem just to keep it going. I'm starting to suspect you're
just a troll.

*My question for you is this; when will you learn to read English? You
act like an uneducated prick who can't read basic English. The
consensus view in the physics community is that the solution to this
problem involves disagreement about simultaneity. I don't see this as
correct. For example, that's what Quentin wrote several times, mocking
me, and that's what a link claimed, without proof, which someone
posted. And even Jesse, if I read him correctly, claims that the
result in one frame must be false if there's no simultaneity. So
that's why I posed the question to you, an alleged expert who teaches
relativity. I am NOT a FUCKIN' troll! The only problem here is that
YOU cannot read plain English, despite being educated at a great
university. FU, AG*
*I read English just fine and reading what I wrote I see that I did not
say the events were simultaneous in the car frame. You just made that
up to keep this ridiculous thread going. Troll!
Brent
*
why is it claimed that the solution to the problem, whatever it
is, depends on disagreements of simultaneous events, when there
are none? And if we get different results for fitting in the
garage, where, for example, the car never fits, is there anything
about this result that implies something contradictory or
paradoxical? AG
