Muon g-2 Experiment Achieves Record Precision, Easing Physics Puzzle

Physicists used antimatter, supercomputers, and giant magnets to resolve a 20-year-old mystery about the muon's magnetism, which could have indicated new physics related to dark matter. Recent experiments and simulations have clarified the discrepancy, but the question of potential new particles like the dark photon remains open, offering clues about dark matter.
