The Relativity of Simultaneity is a Mistake
Thomas E. Phipps
Special relativity theory employs two types of time, invariant proper time (different for each differently-moving particle) and non-invariant frame time. A return to the simplicity of a single invariant time parameter is offered by the GPS method of correcting clock running rates so as to compensate environmental effects due to motion and gravity. Parameterizing timekeeping in terms of a single time allows restoration of distant simultaneity and a surprising number of other amenities of pre-relativistic physics.
