Quote - Do you think that Michelson-Morley were comformed with the failure of their experiment and were happy with Einstein's explanation and then dedicated to the garden of their houses ?  Of course not ! They continued their work, revised their failled experiment, created new experiments and in 1926 they had success and were able to measure the absolute speed of Earth. Everybody knows about their failed experiment, but nobody knows about their successful experiment.

You know there's this thing called Google and it's really easy to check your non-facts, right?

Morley was not convinced of his own results, and went on to conduct additional experiments with Dayton Miller. Miller worked on increasingly large experiments, culminating in one with a 32 m (effective) arm length at an installation at the Mount Wilson observatory. To avoid the possibility of the aether wind being blocked by solid walls, he used a special shed with thin walls, mainly of canvas. He consistently measured a small positive effect that varied with each rotation of the device, the sidereal day and on a yearly basis. His measurements amounted to approximately 10 km/s instead of the nearly 30 km/s expected from the Earth's orbital motion alone. He remained convinced this was due to partial entrainment, though he did not attempt a detailed explanation.

Though Kennedy later also carried out an experiment at Mount Wilson, finding 1/10 the drift measured by Miller, and no seasonal effects, Miller's findings were considered important at the time, and were discussed by Michelson, Lorentz and others at a meeting reported in 1928 (ref below). There was general agreement that more experimentation was needed to check Miller's results. Lorentz recognised that the results, whatever their cause, did not quite tally with either his or Einstein's versions of special relativity. Einstein was not present at the meeting and felt the results could be dismissed as experimental error (see Shankland ref below). To date, no-one has been able to replicate Miller's results, and modern experimental accuracies are considered to have ruled them out.[7]

 

Quote - Michelson-Morley were not only the ones, other scientists created other experiments and among them was a guy named Georges Sagnac that in 1913 had also success in measuring the absolute speed of Earth.

No - it was rotational speed, not absolute speed. The Sagnac effect is about rotation - not linear motion. Further, the effect is easily predicted both by relativity theory and traditional Newtonian physics.

Quote - Wiki -  The Sagnac experiment placed a modified apparatus on a constantly rotating turntable; the main modification was that the light trajectory encloses an area. In doing so any ballistic theories such as Ritz's could be tested directly, as the light going one way around the device would have a different length to travel than light going the other way (the eyepiece and mirrors would be moving toward/away from the light). In Ritz's theory there would be no shift, because the net velocity between the light source and detector was zero (they were both mounted on the turntable). However in this case an effect was seen, thereby eliminating any simple ballistic theory. This fringe-shift effect is used today in laser gyroscopes.

All the rest of what you said is just fantasy piled upon fantasy. You haven't got the least little facts right even on the history of relativity, let alone its use in engineering.
