In the Michelson-Morley experiment, the arms of the interferometer were (effectively) 11m each, and the wavelength of the light was 5900A. The experiment showed an upper limit of interference fringe shift of 0.005 fringes. Based on Aether theory, what is the upper limit of the speed of the earth in relative to Aether?
