Einstein's Theory of General Relativity is still one of the pillars of modern physics. But 100 years after Einstein's theory, there's something that seems to undermine everything we thought we knew - Dark Energy. This mysterious cosmic force is not only causing our universe to expand, but this expansion is also accelerating. In this film, BBC's Horizon celebrates the anniversary of General Relativity - and looks at the latest experiments to try and understand Dark Energy.
