Cosmology is the scientific study of the origin, structure, evolution, and eventual fate of the universe. It explores the largest scales of space and time, seeking to understand phenomena such as the Big Bang, cosmic inflation, dark matter, and dark energy. By combining observations from telescopes, satellites, and large-scale surveys with theoretical physics, cosmologists aim to unravel how the universe began, how it has changed over billions of years, and what its ultimate destiny might be. As new data from missions like the James Webb Space Telescope and surveys like DESI emerge, cosmology continues to shed light on some of the most profound questions in science.
