February 2016 marks one of the biggest discoveries in cosmology and astronomy: the LIGO team annouced that they'd detected gravitational waves, 100 years after Albert Einstein predicted them. Scientists believe this could revolutionise how we study the universe. But what are these gravitational waves? How were they detected? And how is the discovery changing our understanding of cosmos? Graihagh Jackson finds out...

One of the big questions in cosmology is what happened at the beginning of the universe? Astrophycisists are edging closer to answering this question - we can now look back to a fraction of a second after the Big Bang. But what happened before that still remains elusive and there are still many loose ends to tie up. In this episode of Naked Astronomy, Graihagh Jackson takes a look at the origins of time...
