The Universe came into being 13.8 billion years ago. At this point, all of existence could be summed up as an endless soup of particles frothing at temperatures many times hotter than the Sun. It was chaos. Fortunately, as the Universe expanded, everything began to cool and the particles stabilised. It was around this time, as disorder gave way to order, that the elements were born. Fast forward to June 2016 and the periodic table of elements was finally completed with the discovery and addition of four new elements. At last we could identify all the ingredients necessary to make a world. But it doesn't stop there. Human ingenuity knows no bounds; we have even begun to invent our own elements and have created an entire science devoted to their study: chemistry.
