Roberts Roberts you are still a freshman among hypnotists in Einstein
criminal cult and do not have the courage to give breathtaking
examples when explaining length contraction. Superior brothers replace
"marking the endpoints of the moving object simultaneously in the
observer's frame" with "closing both doors simultaneously" and so they
can trap a long train inside a short tunnel:

and also a 80m long pole inside a 40m long barn:

"These are the props. You own a barn, 40m long, with automatic doors
at either end, that can be opened and closed simultaneously by a
switch. You also have a pole, 80m long, which of course won't fit in
the barn....So, as the pole passes through the barn, there is an
instant when it is completely within the barn. At that instant, you
close both doors simultaneously, with your switch. Of course, you open
them again pretty quickly, but at least momentarily you had the
contracted pole shut up in your barn."

So Roberts Roberts, by trapping long things inside short things,
superior brothers are able to demonstrate the real grandeur of
Einstein's discoveries.
