A cosmological model is a mathematical representation of the known universe that addresses fundamental questions about the universe's formation, evolution, and large-scale structure. The foundation of the conventional cosmological model is the perfect fluid assumption in Einstein's General Theory of Relativity. Over the past few decades, numerous cosmological models have been put forth in the context of a fundamental theory that is constantly evolving. These models, particularly the Big Bang and inflationary universe models, are briefly reviewed in this article.
