Detailed explanation-1: -Answer. Answer: The Big Bang Theory is: How are Universe began. Need a bit more clarification?
Detailed explanation-2: -According to this theory the Universe expanded from an extremely small, extremely hot, and extremely dense state. Since then it has expanded and become less dense and cooler. The Big Bang is the best model used by astronomers to explain the creation of matter, space and time 13.7 billion years ago.
Detailed explanation-3: -The Short Answer: 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!
Detailed explanation-4: -Simply put, it says the universe as we know it started with an infinitely hot and dense single point that inflated and stretched-first at unimaginable speeds, and then at a more measurable rate-over the next 13.7 billion years to the still-expanding cosmos that we know today.
