An introduction to the time evolution of model universes: https://arxiv.org/abs/2010.16240
Vinicius S. Aderaldo, Victor P. Goncalves
In this paper we describe the evolution of the Universe in terms of the Friedmann equation, which takes into account of the composition and geometry of the Universe. The dependence of the solution on the geometry and composition for different combinations of the basic constituents are discussed. The distinct behaviors for the temporal evolution of the Universe are determined and the scenario predicted by the Standard Cosmology is presented.
