The Concept of Basic Clocks and Simultaneity in TSR

Authors: Per Hokstad

The concept of ‘basic clocks’ was introduced in Hokstad (2018b). These are moving clocks to be applied in the theory of special relativity (TSR). They experience an initial synchronization at a common location, and provide the basis for defining time and simultaneity. Here we further motivate and elaborate the concept, e.g. by utilizing symmetry. We provide a general criterion of simultaneity, for any event on any reference frame of arbitrary velocity. Further we allow a chain of events with successive ‘initial synchronizations’. Such a feature is required in the ‘travelling twin’ example, in order to handle the turning of the twin. Finally, the approach is used to discuss the interpretation of the case of the µ-mesons.
