Default Einstein's Length Contraction Absurdity

All consequences of Einstein's 1905 false constant-speed-of-light postulate are absurd (according to sane people) but Einsteinians would admit absurdity only if the theory is shown to predicts that two observers see incompatible events occurring at the same location (e.g. if the bug from the bug-rivet paradox is squashed according to one observer and alive and kicking according to the other).

See the story starting at 8:34 in this video:

"Einstein's Relativistic Train in a Tunnel Paradox: Special Relativity"

At 9:01 Sarah sees the train falling through the hole without any disintegration. In contrast, in order for Adam to see the train falling through the hole, the train must disintegrate first (9:53).

Adam does see disintegration of the train; Sarah sees no disintegration. Conclusion: Length contraction is absurd and the underlying premise, Einstein's 1905 constant-speed-of-light postulate, is false.

Default Einstein's Length Contraction Absurdity

It follows from Einstein's 1905 false constant-speed-of-light postulate that unlimitedly long objects can be trapped inside unlimitedly short containers (as seen from the quotations below, some Einsteinians teach that the trapped objects are physically compressed while others insist that there is no compression at all):

"How fast does a 7 m long buick need to go to fit in a 2 m deep closet?"

"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. (...) If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped IN A COMPRESSED STATE inside the barn."

Stéphane Durand: "Ainsi, une fusée de 100 m passant à toute vitesse dans un tunnel de 60 m pourrait être entièrement contenue dans ce tunnel pendant une fraction de seconde, durant laquelle il serait possible de fermer des portes aux deux bouts! La fusée est donc réellement plus courte. Pourtant, il n'y a PAS DE COMPRESSION matérielle ou physique de l'engin."

"Einstein's Relativistic Train in a Tunnel Paradox: Special Relativity", see what happens at 7:12

It is not difficult to realize that trapping long objects inside short containers drastically violates the law of conservation of energy. The trapped object, in trying to restore its original volume, would produce an enormous amount of work the energy for which comes from nowhere. Einsteinians don't care - they even teach that length contraction is a geometrical projection, not a physical event:

Tom Roberts: "There is no "physical length contraction" in SR, there is only "length contraction" which is a geometrical projection -- nothing "physical" happens to the object itself."

Yet Lawrence Krauss seems to disagree with Tom Roberts:

Lawrence Krauss demonstrates real length contraction
