So begins Stardust, Brian Cox’s second instalment of the wonderful Wonders of the Universe on BBC One. I highly recommend it and if you have missed it, all three episodes are still available on iPlayer.
The premise of Stardust is that we are all born from the destruction of stars, which sounds far-fetched. But it’s not at all. Brian Cox’s starting point in Wonders of the Universe is also that of Uma Jakobsdóttir in The Human Race: that every atom in our bodies was once part of something else, be it a dinosaur, a dormouse or a tree. Everything is made from the same basic ingredients and chemical elements, which are the building blocks of everything on earth. When living things die, their physical elements are released back into the world so they can continue the cycle of creation, usually as something else. So far, so good?
