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. > In particular, with regard to this discussion, the math that > applies is algebra. The Lorentz equations are algebra. The Galilean > transformation equations are algebra. Algebra is not arbitrary. Perhaps you should find a hobby that doesn't require post graduate education to understand it?

We KNOW from experiment that t' <> t 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.
