The non-displacement of interference fringes after 90 degrees rotation of the interferometer, in Michelson-Morley experiment (MME) was one of the biggest challenges for physics community for several decades. Several theories have been proposed to explain the null result of the MME, including the Lorentz–FitzGerald length-contraction hypothesis, Special relativity (i.e., the theory of independence of light velocity from observer velocity and source velocity without the necessity of the presence of Luminiferous Aether), aether-drag models, and Emission theories. However, it seems that, apart from these theories, there is another way to explain the null result of the experiment. In this article, we propose the theory of "Aether Attached to Earth" or abbreviated AATE. In this theory, Luminiferous Aether is a fact and is a transparent continuous medium that has filled the entire universe and is attached and is locked to the center of Earth and the whole of it, just like an integrated rigid object, is moved along with Earth in space. It’s clear, in AATE theory, the velocity of Earth relative to Aether is zero; Therefore, the null displacement of the fringes can be explained. In addition to explaining the MME, this theory can explain six other important phenomena and experiments such as Sagnac experiment, Michelson-Gale experiment, stellar aberration, Trouton-Noble experiment, Tomaschek and Miller experiments with extraterrestrial sources and De Sitter observations from binary stars. Here you will see that the AATE theory does not experience the failures of previous Aether theories.
