You are entitled to your own opinion but not your own facts.

Did I stutter? Is English a second language for you? Are you a bit slow in
the head? Unless the answer to one of those is 'yes', the meaning of what I
said is abundantly clear.

Wow, a whole one year of college. No wonder you begrudge scientists in
general and 'college graduates' specifically.

Like I said, you have no training in physics. The most you learned in that 1
year was first semester calculus and most likely it was algebra for the non-
science folks.

Perhaps you should find a hobby that doesn't require post graduate education
to understand it?

program like net nanny or something that gets rid of Newton and

Well,your experiment does not change the Galilean transformation
equations. Those equations say t'=t. That means that t' is time on a
clock in S because t is time on a clock in S. So if you scientists
have another clock that runs slower than t'=t, I am going to call it
something other than t'. That is what the axioms of algebra require
me to do. You scientists want to believe in a length contraction, go
ahead and believe in a length contraction. I don't believe in it.

Well, I know there is not a length contraction, if that is what you
are talking about.
