Abstract

The Weyl-Dirac theory of gravitation and electromagnetism is modified by the introduction of a background metric characterized by a scale constant related to the size of the universe. One is led to a natural gauge giving\({{\dot G} \mathord{\left/ {\vphantom {{\dot G} G}} \right. \kern-\nulldelimiterspace} G} = - 5.5 \times 10^{ - 12} y^{ - 1} \). This is smaller by about a factor of ten than the value obtained on the basis of Dirac's large number hypothesis.
