Optical data implies a null simultaneity test theory parameter in rotating frames

The simultaneity framework describes the relativistic interaction of time with space. two major proposed frameworks are differential simultaneity, in which is offset distance “moving” or rotating frames for each “stationary” observer, and absolute not distance. We use Mansouri Sexl test theory to analyze absence spacetime curvature. has four parameters. Three parameters describe effects. fourth parameter, [Formula: see text], was described as a convention on clock synchronization. show that text] convention, but instead descriptor whose value can be determined from extent anisotropy unidirectional one-way speed light. In frames, light by Sagnac effect equation. published equations form series based kinematics framework. Only conventional equation, its associated isotropic two-way light, found match high-resolution optical data. Using we null implies simultaneity. Introducing empirical parameter values into generates rotational Lorentz transformation, implying this transformation accurately
