Under this approach, the expansion is affected by a geometrical deformation induced by the gravitational attraction of the hole, which should be responsible for the k_{R}-non invariant spectrum of galaxies (and likewise of the matter density) today observed.9 pages, 1 figure Accepted for publication in Physics Letters BGeneral Relativity and Quantum CosmologyAstrophysicsHigh Energy Physics - Theorytext
