    "abstract": "There is no aberration of terrestrial sources, because the light-vector has\nan inertial component. A new analysis of the Michelson Morley experiment shows:\nLight propagates anisotropically relative to a moving system, dependent on the\nvelocity and the angle between the velocity and the direction of motion. The\ntwo way (back and forth) velocity is isotropic, but also dependent on the\nvelocity of the frame. There is no Lorentz contraction. - A real ultrasonic\nexperiment shows: Also the propagation of sound follows the given general\nconical section equation and an acoustical Michelson Morley experiment gives\nthe same zero result as the optical experiment in contrast to the school of\nthought. - The theory of relativity is incorrect and the existence of a\nluminiferous ether as a propagation medium and an absolute frame of reference\nis again obvious. Some properties of the ether and a fundamental cause of the\ndependency of the velocity on the mass and the frequency are presented.",
