The story of the evolution of life on earth during one photon’s journey across the universe. Told by Saul Perlmutter who shared the 2011 Nobel Prize in physics for the discovery of the accelerating expansion of the universe. The second movie out of the “Nature Video Lindau Collection 2015” is out. In this series of animated films, Nobel prize-winning scientists talk about work, life and discoveries that change the world. The stories were recorded by our media partner Nature at the 65th Lindau Nobel Laureate Meeting. The whole series of films – made possible through the support by Mars, Incorporated – can be watched here at Nature’s website.
