The Big Bang theory is the prevailing cosmological model explaining the observable universe's origin from an extremely hot and dense singularity approximately 13.8 billion years ago. It describes the universe's expansion and the formation of fundamental particles, leading to the development of galaxies, stars, and planets over time.
