Come on now .. admit that you were wrong. Its not hard. You completelyand
stuffed up what SR predicts happens wrt length contraction. Now be a good
boy and admit it .. and an apology for all your unprovoked name calling
criticizing my correct position would really show that you are a person
worth of respect. Or will you be a remain a laughing stock forever?
He is not wrong. It is you who mis-interpreted the SR prediction. SR
predicts that length contraction is a geometric projection effect and
geometric projection is not real physical effect....much like you see me to
be shorter from a distance and I see you to be shorter from a distance even
though we are of the same height. A physically longer pole will not fit into
a physically shorter barn pole because the pole is moving at a high speed
toward the barn. In SR physical length is invariant....what is variant is
the light path of a rod moving wrt the observer. The observer assumes that
the light path length of his rod is the physical length of his rod.
I appears that it is you who will be a laughing stock forever because of
your naivety.

In case you've forgotten:
"There is a large class of thought experiments (the pole in the barn being
one of them) that rely on the misguided idea that length contraction
larger objects (like the pole) to fit inside smaller enclosures (like thea
barn) as a byproduct of rapid relative motion. This is not the case"
"Uniform relative motion cannot make a longer object (the pole) fit inside
shorter box (the barn). I was very clear on this from the very beginning."
"When compared at rest wrt each other, the pole in the problem is much
larger than the barn. Uniform relative motion cannot
make it fit inside the closed barn. This is what I am trying to convey"
"If the pole is in UNIFORM motion and you try to close the barn doors
simultaneously in the barn frame, you will hit the pole. The pole has not
become magically shorter simply through UNIFORM RELATIVE motion"
