BBC Horizon 2016 The Mystery of Dark Energy 720p x265 HEVCguy

Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up.

The effects of dark energy were discovered in 1998 but physicists still don't know what it is. Worse, its very existence calls into question Albert Einstein's general theory of relativity - the cornerstone of modern physics.

The hunt for the identity of dark energy is on. Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge - someone who can write a new theory explaining the mystery of the dark energy.
