Zwicky postulates the dark matter approach, based on the incompatibility between Newtonian gravity and the residual velocity measured in galaxy clusters. This approach to dark matter has been prioritized over other theoretical alternatives, although dark matter remains undetected directly. We discuss missing mass through large-scale modification of gravity, with the potential for an inverse Yukawa-type field (UYF), varying with comoving distance (null in the inner solar system, weakly attractive at interstellar distances, very attractive in galaxy clusters and repulsive on cosmic scales). The UYF is caused by the large-scale distribution of baryon mass, in the sense of Mach's principle. We obtain that the UYF resolved the incompatibility between the flatness of the Universe and the density of matter in Friedmann-Robertson-Walker cosmology, provides an explanation for dark energy as the cosmic acceleration caused by the large-scale distribution of matter. Also solves the Zwicky's missing mass because Virial's theorem includes an additional term, such that the virial mass is of the order of , five hundred times less than that calculated by Zwicky. X-ray emissions and Faber-Jackson and Tully-Fisher relationships are discussed.
