Science
Our next video episode is an overview of some ideas that underpin cosmology. We'll be returning to these in later editions and in other articles on this blog (eg expansion of the Universe, background radiation, dark matter and distorted space), but for the moment this, hopefully, sets the scene. It's a bit long and I'm afraid I speak a little slowly this time, but with any luck the beauty of the images and the sheer profundity of the subject will carry you through!Download iPod video version.
