This spring, a global collaboration of scientists released a measurement that had the potential to turn physics’ most important theory on its head. The number they revealed described the behavior of a subatomic particle known as the muon, and the big question was whether the measurement would...

Inside a locked cabinet, an envelope held a number that was poised to rock the physics community, regardless of its contents. The value, a clock measurement deliberately hidden to keep physicists’ data analysis unbiased, would be used in a calculation that could either bring one of particle...
