Cosmology of Einstein-Vlasov system in a weak modification of general relativity

General Relativity and Quantum Cosmology 2015-02-11 v2

Abstract

In earlier work it was shown that a weak modification of general relativity, in the linearized approach, renders a spherically symmetric and stationary model of the Universe. This was due to the presence of a third mode of polarization in the linearized gravity in which a "curvature energy" term is present. Such term was identified as the Dark Energy of the Universe. In this letter a more realistic model is discussed. A different cosmological solution to the Einstein-Vlasov System is analysed. This solution shows reasonable results which are within the standard bounds predicted by the cosmological observations.
