Adam Walton in conversation with Welsh astrophysicist Geraint Lewis. He's based at the University of Sydney in Australia but he's in Swansea this week to talk about the history of the universe, from the big bang to today, and to trillions of years into the future to its demise. Geraint talks to Adam about why dark matter is proving to be so elusive to scientists, the mystery of dark energy and how his students create a whole new Universe before breakfast! The programme also ponders whether a better understanding of gravity could hold the key to unlocking many of the mysteries of the cosmos.
