.... quarters, such as for instance, from nucleosynthesis and X ray studies of the amount of baryons in rich clusters of galaxies to the age of Universe crisis, suggest that Omega 0 = 0:6 Gamma 0:7 3 Values in this range are consistent with the ones arising from studies using the Type I supernovae [36] as standard candles that indicate h 0 = 0:67 Sigma 0:07, but are somewhat lower than the values emerging from studies using classical Cepheid variables observed by the Hubble Space Telescope, h 0 = 0:82 Sigma 0:17 [37] 5 (and Omega Matter 0 = 0:3 Gamma 0:4 with h 0 = 0:7 Gamma 0:8) ....
