The Big Bang Theory explains that the universe began as an extremely dense and hot singularity approximately 13.8 billion years ago. Over time, it expanded and cooled, forming galaxies, stars, and planets. Key evidence includes cosmic microwave background radiation and the observable expansion of the universe. While the theory addresses many questions about the universe's origins, some mysteries remain, such as what caused the initial singularity and what happened before the Big Bang.
