What if you spent your life searching for something that might not exist?

Nobody has managed to challenge Einstein's theory of gravity, even though its shocking conclusion is that the majority of the universe's gravity must be due to a mysterious form of invisible matter which nobody has ever observed. But now physics stands at a crossroads. Some of the field's sharpest brains have dedicated their lives to search for this 'dark matter' while others are working on a new theory of gravity. CHASING EINSTEIN follows leading scientists at the largest particle accelerator (CERN), the largest underground labs (XENON), the largest telescope arrays, and the LIGO gravitational wave detector to find out whether Einstein's theory of relativity—as it passes its 100th birthday—stands the test of time. You don't need a PhD in rocket science to let yourself be carried away by this fascinating film documenting the hunt to answer one of the greatest open questions about our Universe.
