Possibility of a gravitational effect in the spectra of quasi-stellar objects. II

For pt.II see Indian J. Pure Appl. Phys., no.12, p.451 of 1974. It is shown that quasi-stellar objects are most probably situated at cosmological distances. The large redshifts of these objects cannot be due to surface gravitational effects. The Hoyle-Fowler model perhaps holds a last hope of attributing redshift to gravity. Different cluster solutions have been analysed to formulate a suitable Hoyle-Fowler model. A modified Hoyle-Fowler model may explain the emission spectrum of quasars, but such a model fails to give a satisfactory explanation of absorption spectra. However, a Hoyle-Fowler model at cosmological distance may possibly explain sharpness and depth of absorption lines. The Hoyle-Fowler model which was originally designed to provide a non-cosmological model of quasi-stellar objects provides a more satisfactory result if it is at a cosmological distance.
