Issues of Conventional Injection-Locked PLLs (IL-PLLs). Time Dilation. Length Contraction. SPECIAL RELATIVITY. Space, time, motion, revisited. Special Relativity Postulates. The laws of physics are same for all observers in inertial reference frames (IRF). General Relativity. Principle of equivalence:. There is no experiment that will discern the difference between the effect of gravity and the effect of acceleration.. Or…. Gravitational and inertial mass are equivalent..
