Description
Summary:With the object of theoretically predicting clusters to be as empirically observed with regard to mass, density and size, a model of non-compact clusters is obtained by adopting the Schwarzschild interior metric inside the cluster, with a Robertson /Walker metric outside. Implications include that there is no scope for the postulation of large amounts of dark matter in clusters; that the mass density of the universe is therefore close to that given by the luminous matter; thus, that the universe is open. Metric conditions, conditions on the clusters, and cosmological parameters and clusters are dealt with separately.
