The Big Bang theory posits that the universe began as a singular, infinitely dense point roughly 13.8 billion years ago. It then rapidly expanded and cooled, leading to the formation of matter, stars, and galaxies. This theory explains the cosmic background radiation and the distribution of galaxies, providing a comprehensive framework for understanding the origins and evolution of the universe.
