The experiment studied the wobble of muons as they traveled through a magnetic field. Casey was alluding to a principle called Lorentz invariance that holds that the laws of physics are the same everywhere. The researchers shot beams of muons into a donut-shaped superconducting magnetic storage ring measuring 50 feet (15 meters) in diameter.
