As was already pointed out, there is a mountain of experimental verification of STR. You're really barking up the wrong tree here. Note also: it isn't clear if Einstein knew about the MMX and regardless, it isn't needed for the formulation of the theory (but does provide good evidence to support it).I am referring to Lorentz contraction without the STR part in it, Remember - without the result from MM that implies that light has a constant relative velocity to the observer regardless of the motion of the observers's inertial system we have NO STR
And also, please note that our guidelines expressedly forbid free-form idle speculation and unverified personal theories. This is a place to learn physics, not a place to indulge your own personal speculations.
