- 1. Cosmology is the study of the origin, evolution, and eventual fate of the universe. It explores questions about the nature of space, time, and matter on a grand scale, seeking to understand the fundamental forces and structures that govern the cosmos. Cosmologists use a combination of theoretical models, observational data, and advanced technologies to unravel the mysteries of the universe, such as the Big Bang theory, dark matter, dark energy, and the formation of galaxies and cosmic structures. By studying the history and composition of the universe, cosmology sheds light on our place in the vast cosmos and our understanding of the nature of reality itself.
