Scientific paper

A critical review of developments in the controversy about the distances of quasars following the 1972 Arp-Bahcall debate is presented. Special attention is given to the results of the Sandage-Tammann papers, which establish the redshift-distance relationship for galaxies to the extent that any 'intrinsic' redshift effect cannot exceed 50 km/sec. Three dissenting points of view focusing on the questions of calibration, the Local Supercluster, and the Rubin-Ford anomaly are examined. The redshift-distance results, together with evidence that quasi-stellar objects occur in galaxies and with luminosities at least ten times that of the galaxy, lead the author to conclude that the redshifts of quasars are cosmological.
