The origin of the universe and everything ...
    The universe is the set of all that exists. Just as the religious, the scientists also present their own theory for the creation of our universe. The most widely accepted scientific theory today is the theory of the'' Big Bang'' (The Great Explosion), which says that13.7 billion years ago all matter was concentrated in the existingcenter of the universe. This area was very hot, and exploded with great pressure, spreading the dark space of the universe and forming, as the passing of many years, all the heavenly bodies.
        After the explosion occurred the formation of galaxies (large clusters of stars) and one of our oldest is called the Milky Way,formed 13.5 billion years ago. Within the Milky Way, several planets formed around a star called Sol wonderful, forming the solar system4.6 billion years ago. One of these planets is around the Sun is ourEarth.
