Derivation of the Tully-Fisher's law from the Theory of Ether
  The astrophysicist S. Mc Gaugh recently published (3) a result raising questions concerning the existence of dark matter and the validity of General Relativity, conclusion of his observations of 47 galaxies. He established the validity of Tully-Fisher's law for all those galaxies, which is unexplained and in contradiction with classical Cosmology based on General Relativity. Moreover, we remind that this classical Cosmology did not solve the enigma of the nature of dark matter, nor the enigma of its invisibility, nor the enigma of the constancy of the curve of velocities of stars in a galaxy. Consequently it appears that a new Cosmology, alternative to the classical Cosmology, is necessary, at least in the field of dark matter. In fact it exists already a new Cosmology, alternative to classical Cosmology and compatible with the Relativity Theory, which is the Cosmology of the Theory of Ether relative to dark matter. This new Cosmology gives the nature of dark matter, the origin of its invisibility and permits to obtain the constancy of the curve of velocities of stars in a galaxy. In this article, after having recalled the theoretical elements of this new Cosmology, we will show that it also permits to obtain theoretically Tully-Fisher's law whose Mc Gaugh observations confirmed the validity. We will note that all the theoretical results used and obtained in this article are compatible with the Special and General Relativity Principles.
