Big Bang Theory

Big Bang theory is the leading explanation for how our universe began. According to the theory, the entire universe began as a tiny singularity that went through an explosive expansion 13.8 billion years ago, gradually expanding into the cosmos we see today. Today, astronomers can detect an "echo" from the Big Bang in the cosmic microwave background, a phenomenon that can be detected with radio telescopes. Big Bang Theory is also the name of a popular CBS sitcom about scientists, where several real-life scientists and astronauts have appeared.
