Stars, Wormholes and our Expanding Universe - a podcast by Dr Chris Smith

Are Orion's stars shrinking? What are wormholes and do they really exist? What is our universe expanding into? We tackle these cosmic conundrums on this weeks show, as well as find out why light travels faster than sound, if everything spins in space, why TV adverts sound so loud and we investigate the existence of the Bermuda Triangle!
