And still nobody gives a shit.

Rigorous experiments on Einstein's postulates have failed to find a
flaw in any of them.

That's the bottom line - Einstein's theory predicts experimental
results - Pentcho predicts exactly nothing despite
the endless posturing and baiting of supporters of Einstein's Theories.
