Professor Brian Cox on 6Music's Shaun Keaveny Breakfast Show this Christmas Day
How does Santa Claus deliver all of those presents? What's the science behind the Star of Bethlehem? How does Brian take his cheese? This clip doesn't answer any of those questions, but join Shaun Keaveny this Xmas Day with special co-presenter Brian Cox as they discuss all things space, satellites and the science behind Christmas. Also expect Brian getting his sums in a muddle, talking about his days in D:Ream and a very special Song of Praise. And mince pies. Tune in from 7am this Xmas Day www.bbc.co.uk/6music
