Large Hadron Collider restarts to push physics to the edge

Scientists overseeing the largest particle accelerator on Earth switched it on for the first time in three years this weekend to solve some of the biggest mysteries in physics. 

The Large Hadron Collider (LHC), the powerful particle accelerator located at CERN near Geneva, Switzerland, restarted on Friday (April 22) after a three-year shutdown for maintenance and upgrades. The reactivation kicked off what scientists call Run 3, the LHC’s third science run, which will perform experiments through 2024.
