How Big Is Our Universe?

In 1977, Charles and Ray Eames, hugely influential American designers, released one of the most elegant and creative pieces of science communication of modern times - Powers of Ten. It took the viewers on a journey from a picnic blanket near Lake Michigan to the edge of the known Universe, and back again. Over 40 years later, as a humble homage to this groundbreaking film, Professor Brian Cox takes a similar journey through time and space, explaining how our understanding of the Universe has changed along the way.
