The human race has succeeded in explaining nearly everything in this universe using mathematical formulae. Yet there is one place that remains shrouded in mystery -– black holes. Physicists believe that if they could discover a formula that explains the center of black holes, the last remaining mystery of the universe could finally be unraveled -– how the universe came into being. Their attempts have been mired by unforeseen pitfalls but with the development of superstring theory, physicists have arrived at a formula that could finally end their century-long search. What the formula described was a world beyond our wildest imaginations. This is the incredible story of physicists like Einstein, Hawking and the superstring theorists who have endeavored to solve the mystery of the origin of the universe.

Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.
