Concordance cosmology without dark energy
According to the separate universe conjecture, spherically symmetric sub-regions in an isotropic universe behave like mini-universes with their own cosmological parameters. This is an excellent approximation in both Newtonian and general relativistic theories. We estimate local expansion rates for a large number of such regions, and use a scale parameter calculated from the volumeaveraged incre...
متن کاملGravitational Energy as Dark Energy: Concordance of Cosmological Tests
We provide quantitative evidence that a new solution to averaging the observed inhomogeneous structure of matter in the universe (Wiltshire 2007a,b), leads to an observationally viable cosmology without exotic dark energy. We find concordance parameters which simultaneously satisfy three independent tests: the match to the angular scale of the sound horizon detected in the cosmic microwave back...
متن کاملA new basis for cosmology without dark energy
It is shown that small quantum effects of the model of low-energy quantum gravity by the author give a possibility of another interpretation of cosmological observations without an expansion of the Universe and dark energy. Twenty years ago it was difficult to suppose that cosmology may dictate fundamental tasks for other fields of physics, but now many people are searching for dark matter and ...
متن کاملCosmology and Dark Energy: Theory
We present a very brief and incomplete overview of the on-going theoretical activity aiming at providing an explanation for the (at least apparent) acceleration of the universe. We discuss the issue of the cosmological constant amplitude, describe some inhomogeneous cosmology models, present some quintessence and other dark energy models, and say a few words on non-minimal gravity. We mention t...
متن کاملSupersymmetric Cosmology and Dark Energy
Using the superfield approach we construct the n = 2 supersymmetric lagrangian for the FRW Universe with perfect fluid as matter fields. The obtained supersymmetric algebra allowed us to take the square root of the Wheeler-DeWitt equation and solve the corresponding quantum constraint. This model leads to the relation between the vacuum energy density and the energy density of the dust matter.
