Physicists from all over the world in search of the theoretical Higgs particle collaborated on the planning and construction of the 18-mile-long Cern Large Hadron Collider. Situated in an underground complex near the Franco-Swiss border, it’s allegedly the biggest, most expensive scientific experiment ever made. The idea was to recreate conditions immediately after the Big Bang, allowing a closer understanding of the origin of matter. Physicist-turned-filmmaker Mark Levinson was there with his cameras when the collider went online, and he found a way of approaching the experiment as an epic adventure story, involving multiple setbacks, mysteries, and—according to hysterical press accounts—the possible end of the world as we know it. Fortunately, one doesn’t need a Ph.D. in particle physics to keep up with a documentary as thrilling as any fiction.
