摘要

Local space volumes in which Einstein's antigravity due to dark energy is stronger than Newton's gravity from dark energy and baryons is predicted, in which the nearest such region is located at a distance of 1±3 Mpc from the Milky Way. Each galaxy of the group and the flow have been studied in detail by Karachentsev and colleagues using the HST and other big telescopes. In particular, distances to Local Group galaxies and galaxies in the recession flow have been measured with a record accuracy of 10%. The group-flow system can be essentially described by a nonlinear spherically symmetric theoretical model. The group and flow are embedded in the cosmic dark energy background with the local energy density. The results show that for the assumed local dark energy density, the zero-gravitation radius is very close to the radial size of the Local Group. A new type of cosmic motion local recession flows accelerated by dark energy has been discovered in the antigravity regions.
