The scientific study of the universe is known as cosmology. This branch of astronomy focuses on the origin, evolution, structure, and eventual fate of the universe. Cosmologists seek to understand large-scale phenomena such as the Big Bang, cosmic expansion, and the distribution of galaxies and dark matter. They utilize mathematical models, observations, and experimental data to develop theories about the universe's fundamental components. Cosmology intersects with various fields, including physics and philosophy, making it a profound area of exploration that addresses humanity's fundamental questions about existence and the cosmos.
