RAS public lecture, 14 April 2015
by Dr Stuart Clark
It is less than a century since Albert Einstein gave the world the mathematical tools to understand the Universe. In that time, astronomers have developed the theory that our cosmos was born in a titanic release of energy about 14 billion years ago. But why can't they fully prove this Big Bang theory? What pieces are missing from this puzzle and when might we uncover them? This talk will explain the great discoveries we have made, the mysteries still to solve and the questions that we may never be able to answer about the birth of our Universe.
