After a two-year shutdown for upgrades and maintenance, the Large Hadron Collider (LHC) — already the world’s largest and most powerful particle accelerator — is back online and more powerful than ever. The LHC’s particles, which whiz around a 17-mile loop at almost light speed, will now boast nearly twice the collision energy. While the 2012 discovery of the Higgs boson particle was a landmark event, it was basically expected. Physicists hope that with bigger energies come bigger findings: brand-new particles, evidence for theories beyond the Standard Model (the current paradigm) or even the discovery of dark matter’s identity. Hold on to your protons.
