The Dark Side of the Universe with Sylvia Rosenblum

Professor Geraint Lewis brings us the sixth and final part of this series, The Stuff of the Universe. Each episode, we have looked at smaller and smaller stuff and in this episode, we don’t get smaller, just weirder, according to Geraint and weirder is dark matter and dark energy. It’s like finding a piece of a game we don’t know how to play!
