The origin of the universe theory is primarily explained by the Big Bang Theory. According to this theory, the universe started from an extremely hot and dense singularity around 13.8 billion years ago and has been expanding ever since. This expansion leads to the cooling of the universe, allowing matter to form galaxies, stars, and planets. Key evidence includes cosmic microwave background radiation and the redshift of galaxies.
