Of course the Michelson-Morley experiment supports Einstein's 1905
constant-speed-of-light postulate. But Pentcho's thread title is
fraudulent baloney.

What's so strange about that? Nothing at all really.

When did Pentcho Invalid ever use logic?

Nothing invalid about that. Anyone with a smattering of mathematical
ability can prove that.

Correct.

Completely false baloney as anyone with a smattering of mathematical
ability can demonstrate.

Why would there be any length contraction if c' = c + v? This is proof
that Pentcho's "logic" is invalid.

Length contraction is a consequence of nonsimultaneity between frames
which, in turn, is a consequence of c' = c. So it is redundant to
specify both c' = c AND length contraction. Once more Pentcho's illogic
rears its ugly head.

There is no such assumption. The assumption is c' = c. Length contraction
is a consequence. Once more Pentcho's illogic rears its ugly head.

Once more Pentcho's stupidity and illogic rears its ugly head :-)))
