In the middle of the desert are huge, 4km long concrete tubes that are part of a giant machine running the most precise experiment humans have ever built.
Inside the tubes is a pipe with fewer particles in it than the International Space Station flies through and at the end are some of the smoothest mirrors ever made.
Scientists fire a powerful laser down the pipes, bouncing it back and forth… building up power, until they bring those beams back together…to discover something that 100 years before scientists said was impossible to find.
