World’s largest particle smasher halts for upgrade to boost hunt for dark matter

CERN shuts the LHC until 2030 for a $1.5B upgrade to increase collision luminosity 10x (140-200 vs 60 per event). The upgrade requires real-time AI to filter billions of collisions per second—a critical benchmark for AI-driven physics data selection.
