Dirac's Cosmology and the Dating of Meteorites

Nature volume 183, pages 170–171 (1959)Cite this article

Abstract

IT was long ago suggested by Dirac1 that, from considerations based upon the sizes of the important physical and astrophysical constants, there were reasons for believing that the gravitational constant, when expressed in atomic units, was not a true constant but that it varied inversely with the age of the universe. It has been pointed out that of the other physical constants, only the weak coupling constant would be expected to vary strongly with time, assuming the correctness of the Dirac hypothesis2.
