Using Time Drift of Cosmological Redshifts to find the Mass-Energy Density of the Universe
Abstract
In this paper we show that the mass-energy density of the Universe can be fully determined in terms of the cosmological redshifts, their time drifts and angular-diameter distance (observer area distance). Besides providing an indirect measurement of the mass-energy density of the Universe, we show how one can use the time-drift of the cosmological redshifts as a replacement for the mass-energy density element in the minimally required data set to construct an spherically symmetric Lema\tre-Tolman-Bondi (LTB) model for the Universe in observational coordinates.
