Cosmologists are scientists who study the universe as a whole, including its origins, evolution, structure, and eventual fate. They seek to understand fundamental questions about the cosmos, such as the nature of dark matter and dark energy, the formation and evolution of galaxies, the cosmic microwave background radiation, and the overall geometry of the universe. Cosmologists often utilize principles from physics and astronomy, employing both observational data and theoretical models to develop their understanding of the universe.
