The possibility that Newton’s gravitational constant, G, varies in time was suggested theoretically by Dirac on numerological grounds.1) Brans and Dicke2) have proposed a specific scalar-tensor theory which predicts a variation, with time, in G; and it is also true that most metric theories of gravity3) make such a prediction.
