The Big Bang theory is today’s dominant scientific theory about the origin of the universe. It states that the universe was created from an infinitely hot and dense subatomic ball‚ which once exploded not only created energy and matter‚ but space and time itself. This is estimated to have happened around 14 billion years ago. 300‚000 years after the big bang took place the plasma of elementary particles had cooled to 3000K‚ during which atoms began to form as electrons came into orbit around protons
