Scientific discoveries come in many forms, like the surprise of radioactivity or the long search for the predicted Higgs boson. But some discoveries are mixed, with a hint in the data pointing to future measurements that can take years. A scientific study of the third kind is getting underway now, and the payoff for physics could be huge.

On Tuesday (Feb. 6), a collaboration of 190 scientists operating at Fermi National Accelerator Laboratory in Illinois began using an array of magnets arranged in a ring 50 feet (15 meters) in diameter to make one of the most precise measurements ever performed. In this research, called the g-2 experiment (pronounced "g minus 2"), or just g-2 for short, scientists will measure what is called the anomalous magnetic moment of the rare subatomic particle called a muon, which is a heavy cousin of the electron and spins sort of like a top. The muon, however, exists for only 2.2 millionths of a second when at rest. [Beyond Higgs: 5 Elusive Particles That May Lurk in the Universe]
