Light years

An exploration of man's fascination with light. Here is the story of the greatest puzzle in our universe: what is light? "Light Years" explores our understanding of light from the spiritual interpretations of the Neolithic worshippers at Stonehenge, the Ancient Egyptians and the Mayans, through our first scientific attempts to understand light, and up to the present day.

It looks over the shoulders of the great revolutionaries of light theory Bacon, Galileo, Newton, Faraday, Maxwell, Einstein, and Feynman and traces the evolution of light driven-devices from the camera to the laser.

This piece of real-life science-fiction explains the mind-bending advances of quantum physics that put light at the heart of all matter and which could finally make time travel possible and change the world as we know it forever. "Light Years and Time Travel" is an engaging survey of everything we know of the universe's most enigmatic substance.
