How Big is the Universe?: it is impossible for the human mind to grasp just how big the universe is, but astronomer Pete Edwards gives it his best shot. Along the way, he explains how astronomers have learned to measure the distance to the stars, using concepts such as parallax and redshift.The Expanding Universe and the Big Bang: Pete Edwards and cosmologist Carlos Frenk explain why we think the universe started with a Big Bang and how it grew from almost nothing into the vast web of stars and galaxies we see all around us. They also reveal how at Durham University they are creating their own universe inside a supercomputer.
