Abstract. The results of the Michelson-Morley Experiment (MMX), allegedly showing that an aether medium for the propagation of light did not exist, were interpreted by Einstein under the constraint of a constant light speed. This led him to invent Special Relativity, not necessarily the simplest or most logical explanation, as would have been recommended by Occam’s Razor. MMX is revisualized here, relaxing these constraints to show what might have been the better conclusion, or at least dismissal of the MMX as a basis for inventing Special Relativity.
