ON THE PRINCIPLE OF MICHELSON-MORLEY EXPERIMENTS

Solving the null results of Michelson-Morley experiments that have puzzled physicists for more than a century,the article sets out one of the universal fundamental principles in physics——the principle of motion superposition.It can be stated as: the total motion of a particle is the superposition of its independent motions simultaneously,motions at different times or at different places or of different objects can never superpose.The principle of Michelson-Morley experiments is totally wrong because it miscomputes the optical path difference,which is a mere function of distances and refraction indexes of mediums and is independent of time.The Michelson-Morley experiments never disprove the existence of ether.
