"Emission theory, also called emitter theory or ballistic theory of light, was a competing theory for the special theory of relativity, explaining the results of the Michelson–Morley experiment of 1887...The name most often associated with emission theory is Isaac Newton. In his corpuscular theory Newton visualized light "corpuscles" being thrown off from hot bodies at a nominal speed of c with respect to the emitting object, and obeying the usual laws of Newtonian mechanics, and we then expect light to be moving towards us with a speed that is offset by the speed of the distant emitter (c ± v)." https://en.wikipedia.org/wiki/Emission_theory
How is Newton "explaining the results of the Michelson–Morley experiment of 1887"? He assumes that the light emitted in the direction of the Earth orbit has a variable speed c+v (300000+30 km/s), does calculations and predicts that the two perpendicular beams will return simultaneously (null result). The experiment confirms Newton's prediction.
Just for the sake of argument, Newton next assumes that the light emitted in the direction of the Earth orbit has a constant speed c (300000 km/s), does calculations and predicts that the two perpendicular beams will NOT return simultaneously. This time the experiment refutes Newton's prediction.
