The world's two most advanced particle detector experiments -- ATLAS and CMS -- have both detected signs of a particle that eluded physicists for almost a half century -- a particle researchers suspect is the Higgs boson.
I. Hunting for Higgs -- Inside the Most Expensive Machine Created by Man
The two detectors are housed within a 17 mile in circumference underground tunnel in the Alps, a tunnel which is chilled to temperatures colder then outer space. The particle accelerator and attached detection apparatus is a triumph of engineering, and at $10B USD is the single most expensive piece of laboratory equipment in the history of mankind.
Brought online in 2008, the collider suffered from early hiccups, typical of large particle accelerators. But before long it was setting records and gathering data which led to the discovery of new exotic particles.
