The Big Bang theory explains how the universe started in a scientific way. According to this, many astronomers believe that the universe started about 14 billion years ago in a big bang. Our entire universe was believed to be inside an extremely small and dense bubble.
All of a sudden, it exploded and since then, it kept on growing at an amazingly high rate. This explosion created a very hot, but very small, ball of energy and matter. All scientists believe that at the time of the Big Bang, space, energy and all of the building blocks of life came into existence.
