It seems impossible, but it's true: everything started when everything was in the same place. We don't know how it appeared, but we know that the Universe had its origin in a very small space. Smaller than a grain of sand or the tip of the sharpest pencil in the world! Impossible tells the story of the Universe, up close (and several light-years away), from the Big Bang to the appearance of a man. A journey between particles, stars, and dinosaurs.
