Justification of rotation curves of galaxies without dark matter, based on the new gravitation theory, starting from the ether presence after correcting Michelson’s analysis errors from 1881/87 experiments.

Sections 2-6 constitute actualizations of our previous works necessary to identify the electric dipole force FDC that creates the current velocities of bodies in galaxies, replacing the Newtonian gravitational force FN.The new theory of gravitation (NTG16) is part of a new physics theory (NTP16), which emerged from our discovery of Errors 1 and 2 in Michelson’s analysis of his interferometer experiment from 1881/1887.By correcting Michelson's errors, we were able to reintroduce ether into physics in the form of the model proposed in 2016, HM16. After HM16 was completed, NTG16, which led to the modification of the calculation method of the current gravitational force FN according to Newton’s law between two masses, resulting in a new force of universal attraction, which was created between the electric dipoles of the masses, FDC, based on the completed Coulomb force FCC.According to NTG16, the new dipole force FDC was greater by approximately 60% (preliminary) than the gravitational force FN when applied to two masses located at galactic distances.By applying the new force FDC, some changes will also result in the theoretical rotational velocity vr curves of the galaxies, and the new curves of the theoretical velocities will correspond better with those of the real velocities of the galaxies measured by the astronomers.The ad hoc hypothesis of the existence of dark matter (DM) in the universe, which was introduced by astronomers after 1930 to explain the real velocity curves of galaxies, is therefore called into question.
