H0, why the differences?. (1993). Revista Mexicana De Astronomía Y Astrofísica, 26(1), 73-78. https://astronomia.unam.mx/journals/rmxaa/article/view/1993rmxaa..26...73v
Abstract
An up-to-date review of the present status of the distance scale problem is given. The local (v0 < 10000 km s-1) value of the Hubble parameter is found to be H0 = 83±6 km s-1Mpc-1. A global (v0 > 10000 km s-1) H0 = 76±9 km s-1Mpc-1 is derived. The reasons for some deviant results recently obtained by others are discussed. The main culprits appear to be (1) the assumption that SNeIa are good standard candles with uniform colors, and (2) the belief that the diameters of ScI galaxies are good yardsticks.Similar Articles
