Order-unity argument for structure-generated extra expansion


Abstract in English

Self-consistent treatment of cosmological structure formation and expansion within the context of classical general relativity may lead to extra expansion above that expected in a structureless universe. We argue that in comparison to an early-epoch, extrapolated Einstein-de Sitter model, about 10-15% extra expansion is sufficient at the present to render superfluous the dark energy 68% contribution to the energy density budget, and that this is observationally realistic.
