Most people have heard of the Big Bang theory, but is it just a theory? In this talk we will discover why scientists have come to regard the Big Bang as the fundamental background to all our ideas about how the Universe works. Many different strands of observation and theory weave together to give us a picture of the history and evolution of the Universe that is surprisingly consistent and successful. We will also talk about the aspects of the Big Bang that we don’t yet understand, and whether we are likely to get the answers soon.
