A bug is alive in one reference frame and squashed in another:
"In an attempt to squash a bug in a 1 cm deep hole, a rivet is used. But the rivet is only 0.8 cm long so it cannot reach the bug. The rivet is accelerated to 0.9c. [...] The paradox is not resolved."
In the rivet's frame, "the end of the rivet hits the bottom of the hole before the head of the rivet hits the wall" - the bug is squashed. In the bug's frame, "the rivet head hits the wall when the rivet end is just 0.35 cm down in the hole" - the bug remains alive.
Of course Einsteinians do realize that the bug being squashed in the rivet's frame and alive in the bug's frame is fatal for Divine Albert's Divine Theory. So they resort to an idiotic ad hoc "requirement":
The rivet shank gets longer than itself.
Now poor bug is squashed in both frames and Divine Albert's Divine Theory is saved:
"In fact, special relativity requires that after collision, the rivet shank length increases beyond its at-rest length d."
"Unfortunately, though, the rivet is fired towards the table at a fair percentage of the speed of light. It's somewhat typical of this book that all it tells us about the speed is that γ is 2, which doesn't really give you an idea of how fast the rivet is going, but if my back of an envelope calculations are right, this is around 0.87 times the speed of light. Quite a fast rivet, then. [...] But here's the thing. Just because the head of the rivet has come to a sudden stop doesn't mean the whole rivet does. A wave has to pass along the rivet to its end saying 'Stop!' The end of the rivet will just keep on going until this wave, typically travelling at the speed of sound, reaches it. That fast-moving end will crash into the beetle long before the wave arrives. [...] Isn't physics great?"
Note that the end of the rivet keeps on going at 87% the speed of light and a wave traveling at the speed of sound is chasing it in order to stop it! We all live in Einstein's schizophrenic world, don't we?
