Detailed explanation-1: -Summary. The Big Bang theory states that the universe began as a point and expanded outward. No one can know what came before the Big Bang because there is no remaining evidence. The tiny bit of background radiation in the universe is energy remaining from the Big Bang.
Detailed explanation-2: -Many cosmologists think its origin lies in so-called quantum uncertainty, which is known to allow energy to emerge literally from nowhere. What isn’t clear, however, is why this cosmic energy persisted long enough to drive the Big Bang.
Detailed explanation-3: -The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now-and it is still stretching!
