In this episode, Professor Brian Cox explores our origins, place and destiny in the universe. We all start our lives thinking that we are at the centre of the universe, surrounded by our family and the world as it spins around us. But the urge to explore is strong. Brian tells the story of how our innate human curiosity has led us from feeling that we are at the centre of everything, to our modern understanding of our true place in space and time that we are living 13. 8 billion years from the beginning of the universe, on a mere speck of rock in a possibly infinite expanse of space.
