A symmetry associated with this theory was tested by looking at frequency shifts in Zeeman splitting, and was carried out by Hughes and Drever.
This theory's predictions were tested by measuring the kinetic energy of electrons hitting an aluminum disc in an experiment by Bertozzi. A symmetry associated with this theory was tested by looking at frequency shifts in Zeeman splitting, and was carried out by Hughes and Drever. Because the Poincaré group is non-abelian, this theory yields a reduction in spin orbit interactions. This theory explained the mean lifetimes of (*) muons as observed in the RossiHall and FrischSmith experiments. The invariant metric element in this theory is the spatial length squared minus the time squared. This theory, whose mathematical setting is Minkowski space, predicts that objects at high velocities undergo length contraction. For 10 points, what theory postulates the invariance of the laws of physics in all inertial reference frames and the constancy of the speed of light?
