Astrophysical Consequences of Dirac's Hypothesis of a Variable Gravitational Number

Dirac's hypothesis of a variable gravitational number K leads to astrophysical consequences, which can be verified and which suggest that one interpret the quasi-stellar objects as early stages of normal galaxies. Conversely, one may see in these consequences an indication that the gravitational number K, according to the new presentation of Dirac's hypothesis by Jordan, Brans, and Dicke, is a function of the age of the Universe and decreases with increasing age of the Universe
