Physicists have had a good run recently at detecting the seemingly undetectable. First there was the Higg's Boson, confirmed by experiments at the Large Hadron Collider in 2012, nearly 50 years after it existence was first proposed. Then in 2015 the LIGO detectors found gravitational waves, a century after Einstein predicted them. Both discoveries were rewarded with Nobel Prizes.

If all goes to plan, in the next few years dark matter will move from the realm of the hypothetical to the observable, opening a new era in experimental physics, and a major step towards a fundamental theory of nature.
