Abstract
ASTROPHYSICAL evidence in favour of the thesis that an appreciable amount of the heavy elements was produced in a giant explosion in the nucleus of the galaxy about 7 × 109 yr ago has been given by Unsöld1. Cosmochemical arguments could support Ambartsumyan's concept2 of the presence of massive bulks of prestellar matter in the nuclei of the galaxies. The latter concept has now received further support from the calculations of Saakyan and Mnatsakanyan3, who have reported on the possibility of hydrostatic equilibrium of superdense matter bulks of arbitrary mass in the framework of a slightly modified general relativity theory with variable gravitational constant G.
