The Big Bang Theory is a scientific explanation for the origin and evolution of the universe. According to this theory, the universe began approximately 13.8 billion years ago as an exceedingly hot, dense point known as a singularity. This singularity then expanded rapidly in a process known as the Big Bang, leading to the formation of the universe as we know it.
