Explaining the Supernova Data without Accelerating Expansion
The 2011 Nobel Prize in Physics was awarded “for the discovery of the accelerating expansion of the Universe through observations of distant supernovae.” However, it is not the case that the type Ia supernova data necessitates accelerating expansion. Since we do not have a successful theory of quantum gravity, we should not assume general relativity (GR) will survive unification intact, especia...
متن کاملAccelerating cosmological expansion from shear and bulk viscosity.
The dissipation of energy from local velocity perturbations in the cosmological fluid affects the time evolution of spatially averaged fluid dynamic fields and the cosmological solution of Einstein's field equations. We show how this backreaction effect depends on shear and bulk viscosity and other material properties of the dark sector, as well as the spectrum of perturbations. If sufficiently...
متن کاملAccelerating Expansion of the Universe with Nonlinear Spinors
The accelerating expansion of the present Universe is an exciting challenge to the standard cosmology, which reflects that our current theories on matter have some incompletion. In this paper, we analyze the cosmological model with nonlinear spinor fields source in detail. The results may be able to provide a natural explanation for the puzzles of the acceleration and negative pressure. PACS nu...
متن کاملCardassian Expansion : a Model in which the Universe is Flat , Matter Dominated , and Accelerating
A modification to the Friedmann Robertson Walker equation is proposed in which the universe is flat, matter dominated, and accelerating. An additional term, which contains only matter or radiation (no vacuum contribution), becomes the dominant driver of expansion at a late epoch of the universe. During the epoch when the new term dominates, the universe accelerates; we call this period of accel...
متن کاملGeneralized Cardassian Expansion: a Model in Which the Universe Is Flat, Matter Dominated, and Accelerating
The Cardassian universe is a proposed modification to the Friedmann Robertson Walker equation (FRW) in which the universe is flat, matter dominated, and accelerating. In this presentation, we generalize the original Cardassian proposal to include additional variants on the FRW equation; specific examples are presented. In the ordinary FRW equation, the right hand side is a linear function of th...
