What is another word for Michelson-Morley experiment?
Pronunciation: [mˈɪt͡ʃɛlsənmˈɔːlɪ ɛkspˈɛɹɪmənt] (IPA) 
The Michelson-Morley experiment, also known as the MM experiment, is one of the most important experiments in modern physics. It is a landmark experiment that aimed to detect the presence of the luminiferous ether, a supposed medium for the propagation of light waves. While the MM experiment failed to detect the ether, it led to the development of the theory of relativity and the concept of the constant speed of light. Synonyms for the Michelson-Morley experiment include MMX, Michelson experiment, Michelson-Morley interferometer, and the MM test. All of these synonyms refer to the same vital experiment that transformed our understanding of the fundamental nature of space, time, and light.
