The problem is that your head is so full of doctrine that it now cant discern the difference between rational claims and religious faith based beliefs.
What part of Galilean relativity don't I understand, in your opinion?
You are displaying your inability to think rationally when you said, "the M&M experiment does show that the Earth is not moving through aether", and assuming that this proves something about lights velocity in various imaginary frames of reference. It demonstrates nothing of the sort. It only demonstrates that either the equipment was not suitable to detect the aether, or that no aether was there to detect. That's the only conclusion you can make.
Again you seem to think that I am not understanding Physics, based on the fact that I don't accept your (Einsteins) wacky claims.
Ever thought that its you who is missing the point?
Understanding (read, "UNDERSTANDING") the M&M experiment requires not one line of algebra, and no math. Its able to be understood as a set of various Physics principals. If you don't get the EXPLANATION of the Physical Process well documented, then your Math is going to be garbage.
This is the case here, no correct understanding of simple Physics, then jumping into the development of some meaningless, baseless equations.
