Descrição: The structure and evolution of the zero-acceleration surface around wide triple systems of galaxies are studied in detail. (The zero-acceleration surface is the boundary separating regions in which (i) the Newtonian gravitational attraction of the galactic matter and (ii) the Einsteinian universal repulsion of the cosmic vacuum dominate.) For a typical system, this surface is spherical in shape and several megaparsecs in size, and remains nearly unchanged throughout the lifetime of the system. The concept of a boundary surface can also be extended to systems on the largest possible scales, and its general properties are discussed in relation to clusters, superclusters, and voids.
