Which effects of galaxy clusters can reduce the amount of dark matter

Original language description

In 1933, Zwicky observed velocities of galaxies in the Coma cluster which were too high. By means of the Virial Theorem considered in Euclidean space he proposed the existence of dark matter to keep the cluster stable. In this paper we collect several phenomena and facts not taken into account by Zwicky that can partly explain the high calculated mass of the cluster, for instance, dark energy, finite speed of gravitational interaction, gravitational aberration, curved spacetime, the selflensing effect,relativistic effects, decreasing Hubble parameter, etc. Thus, the calculated amount of dark matter in the Coma cluster may be substantially reduced. This also applies for dark matter inside galaxies.
