A machine poised to make science history is now ready to launch. The Large Hadron Collider — a giant machine built 330 feet below the France-Switzerland border — is scheduled to fire up for the first time next month, on Sept. 10. The LHC, as its name suggests, works by smashing tiny particles called “hadrons” together at extremely high energies — higher than has ever been possible before. That, in effect, is what makes it unique and gives it the potential to uncover never-before-found answers.
