In the last episode of his epic journey through the WONDERS OF THE UNIVERSE (Wednesday, August 17 at 10PM ET/PT), Professor Brian Cox travels from the Burgess Shale to the sands of the oldest desert in the world to show how light holds the key to our understanding of the universe. At one of the most magnificent archaeological sites in the world, Cos watches the sun rise during the winter solstice, and demonstrates how the same properties of light that color desert sands and the hues of a rainbow also provide unique insights into the history and evolution of the universe.
Then, by breaking the sound barrier in a fighter jet, he explains how the speed of light allows us to measure distance and time. Finally, with fossils that date back to the Cambrian explosion, he considers how the secrets of light could easily have remained hidden forever if not for the development of eyes. Without adaptations from our distant ancestors some 500 million years ago, we would be unable to observe, capture and contemplate the incredible wonders of the universe that we inhabit.
