摘要：

Recent observational data on the density of the cosmic vacuum are used to obtain an exact solution for the zero-acceleration surface around the Local Group of galaxies. This surface separates the inner region, in which the gravitation of the galaxies dominates, from the outer region, in which the antigravitation of the cosmic vacuum dominates. The zero-acceleration surface is close to a sphere of radius similar or equal to 2 Mpc. The size and shape of the surface have remained nearly constant during the lifetime of the Local Group as a distinct system of galaxies. (C) 2003 MAIK "Nauka/Interperiodica".
