Scientific paper

This paper investigates the reasons for the discrepant results in efforts to derive the Hubble constant from the velocity-distance ratios for individual galaxies. A test is made here by combining redshift and magnitude data for bright ScI galaxies from the RSA with faint ScI galaxies from two catalogs in the literature. It is shown that the method of assigning a fixed to each ScI galaxy in the bright sample (or to any other parameter that might be adopted as a distance indicator) produces an artificially compressed distance scale, imitating a varying Hubble ratio that appears to increase outward. However, adding the bright and faint samples gives a list that approaches a volume-limited catalog for redshifts smaller than ≡4000 km s-1, from which it is demonstrated that the local velocity-distance relation is linear over this redshift range and that the value of the Hubble constant is low. Calibration of the ScI magnitude and redshift data in the υ → 0 limit, using M31, M81, and M101 as calibrators, gives H0 = 42±11 km s-1Mpc-1. The age of the globular clusters is adopted to be 13.5±1 Gyr. The age of the universe is put at 14.9±2 Gyr, giving H0TU = 0.64±0.19 and thereby Ω0 = 1.2 (+3, -0.9).
