As we know, according to Special Relativity, if A and B move relatively to each other, A’s clock will be slower from the point of view of B and vice versa! Well, there is Champeney and Moon experiment. Two observers (detectors) rotate on opposite sides of a rim of a centrifuge: http://iopscience.iop.org/article/10.1088/0370-1328/77/2/318/meta The experiment vividly demonstrates, that there was no relative time dilation. That probably means, that the detectors slow down at the same magnitude bacause motion is absolute, or what? This source http://www.mathpages.com/home/kmath587/kmath587.htm (just below the diagram) also claims: “Qualitatively this applies equally to both the classical and the relativistic treatments. (Since both emitter and receiver have the speed v relative to this system of reference, there is no differential time dilation.)” It is according to Lorentz, not Einstein, isn't it? But what about the Great Science - A is slower than B and B is slower than A?
