The Universe and Everything
Scientists studying nature are getting increasingly good at working out how things work. From the Big Bang Theory to DNA. From the evolution of species to how chocolate can make us happy. We now have a pretty good idea how life works from the smallest chemical action to the largest atomic reaction. It seems as though one day we will know how everything in our Universe works... but there is one crucial element missing. The why. We know that sunlight makes plants photosynthesize carbon dioxide into oxygen. We know that when an electrical spark is applied to gasoline it explodes. We know that when water boils it turns to steam. We know these things and a host of others because we can prove them - every time. But do we know why they happen? Scientists say that these reactions are 'coded' into the makeup of the elements. That these reactions are inevitable, given the right circumstances. We know that during the Big Bang, for instance, certain elements came toge
