The fourth episode of the documentary series Human Universe by Brian Cox. In this episode we explore our knowledge about our place in space and time. It has only been in recent times, perhaps the last couple of hundred years that we knew we are on a ball of rock, the third outpost in a solar system which orbits the sun.
We take this knowledge for granted but in a hundred years from now theories which are on the fringes of science may well be common knowledge. This documentary is the story of how we are learning about the world around us with ever increasing precision and where it might be leading us.
