This paper presents an empirical test of Schlegel's “interaction interpretation” of the theory of special relativity. Analysis of the UTC time scales maintained at various observatory sites over the world indicates that neither Schlegel's “interaction interpretation” of the theory of relativity nor the conventional “space-time coordinate transformation interpretation” of relativity can significantly improve agreement between the UTC time scales. Instead evidence for the effects of accelerations on clock rates is suggested.

This is a theoretical paper. A little theory goes a long way in history, for me; but it is good to collect as much as is feasible in one paper, so that gaps and inconsistencies can be noticed. I use ‘theory’ in the definite sense of a set of hypothetical statements such that deductions can be made and compared with data, facts, or generalizations obtained in some other way than as derivation from theory. Deductions need not always be rigorous, and (...) there may be two or more ‘solutions’ obtainable, of which the scientist may choose one and discard the rest . I am ignoring the differences between propositions, demonstrations, problems, and the like. Actually there must always be several statements, including rules of procedure, in the set; but often many are assumed and only the new or controversial one is stated as ‘the’ hypothesis of Mr X.
