Nobody has managed to topple Einstein's theory of relativity, even though it leads to the shocking conclusion that most of the universe must be made of mysterious invisible "dark matter." But now physics stands at a crossroads. Some of the sharpest brains in physics have dedicated their lives to search for dark matter while others believe that it's time for a new theory of gravity. Chasing Einstein follows leading scientists around the world on their quest to solve one of the greatest mysteries of Einstein's universe.
