An introduction to the time evolution of model universes
Vinicius S. Aderaldo, Victor P. Goncalves
TL;DR
This paper explains how the Universe's evolution is modeled using the Friedmann equation, highlighting how different compositions and geometries influence its temporal development, and discusses the standard cosmological scenario.
Contribution
It provides an overview of the time evolution of the Universe based on the Friedmann equation, emphasizing the effects of composition and geometry on its dynamics.
Findings
Different geometries lead to distinct evolutionary behaviors.
The standard cosmological scenario is consistent with the Friedmann equation predictions.
The dependence of evolution on universe composition is analyzed.
Abstract
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.
