A Brief Review of the Dynamical Universe in the Early and Late Stages

Authors(1) :-Indranath Bhattacharyya

A dynamical study of the universe is briefly reviewed in the early stage (inflation) as well as in the late era (cosmic doomsday). The cosmological model of the expanding universe, governed by the Friedman equations, is explored. It is indicated that the expansion is proved to be accelerated experimentally. In the early phase, just after the big bang, the expansion of the universe is rapid and approximately exponential, which is termed as inflation. The mathematical formulation and physical significance of the inflation is discussed briefly. A number of inflationary models are also listed. The ultimate fate of the universe is briefed in the scenario of dark energy and phantom energy. The possible singularities, arising in the phantom energy era, are also discussed.
