    "abstract": "Physics textbooks assert that in the famous interferometer 1887 experiment to\ndetect absolute motion Michelson and Morley saw no rotation-induced fringe\nshifts - the signature of absolute motion; it was a null experiment. However\nthis is incorrect. Their published data revealed to them the expected fringe\nshifts, but that data gave a speed of some 8km/s using a Newtonian theory for\nthe calibration of the interferometer, and so was rejected by them solely\nbecause it was less than the 30km/s orbital speed of the earth. A 2002 post\nrelativistic-effects analysis for the operation of the device however gives a\ndifferent calibration leading to a speed \u003e300km/s. So this experiment detected\nboth absolute motion and the breakdown of Newtonian physics. So far another six\nexperiments have confirmed this first detection of absolute motion in 1887.",
