This study explores various cosmological models within the framework of General Theory of Relativity to understand the large-scale structure and evolution of the universe. It focuses on solutions of Einstein’s field equations under different physical conditions, including homogeneous and anisotropic space-times. The role of matter content, dark energy, and cosmological parameters in determining the dynamics of expansion is examined. The work also investigates the effects of viscosity and modified equations of state on cosmic evolution. These models provide insights into early universe behavior, accelerated expansion, and the overall geometry of the cosmos.
