World's Largest Particle Smasher Halts for Four-Year Upgrade to Boost Dark Matter Hunt

The Large Hadron Collider (LHC) at CERN is set to begin a four-year shutdown for renovations aimed at dramatically boosting its collision capacity. This upgrade is intended to enhance the search for dark matter and other fundamental physics mysteries. The work will involve replacing components in 1.2 kilometers of the 27-kilometer tunnel and installing new superconducting magnets to increase particle collision precision and intensity.
