Okay that was funny I can't front

Look, the bottom line is that an equation was found that matched what was observed, but what was observed was misinterpreted.
That's why you guys think you have the answer to everything, because you parrot whatever NASA tells you that you see along with an accompanying equation, even though you all are just as baffled as them when there are anomalies that don't match up with the expected mathematical outcome. There is plenty of legitimate pushback to Einstein's theory. And yes, even though E = MC Ren

was derived from relativity theory, later on in his life Einstein HIMSELF also derived it
without relativity. And Michelson thought there should be a variation in the observed speed of a light beam's back and forth motion within the interferometer, which was supposed to be produced by the earth's forward motion during the period of transmission. The difference in light speed was supposed to produce a "fringe shift" in the interferometer, which was sensitive enough to detect it.
But there was no effect. That "null result" fucked up the world of theoretical physics. And further, Michelson never even accepted relativity theory.
