![]() ![]() The corresponding expansion age is T=15.7+/-1.5Gy (with Omega(Matter)=0.3, Omega(Lambda)=0.7), which compares well with the formation time of 15+/-2Gy for the apparently oldest globular cluster M107. For all practical purposes Ho=60 is recommended with a systematic error of probably less than 10%. ![]() No significant metallicity effect on the Cepheid distances seems to be indicated. 1999) is flatter than anticipated, which tends to increase the above values of Ho by 3.4 units. Of course you could say the path is about finding God, and that's also true. This illusion is the cause for all suffering and all of the bad things we associate specifically with the human condition. The intermediate expansion field (1200 10days, as judged from OGLE data (Udalski et al. The main illusion is that you are a separate self, isolated from the environment and others. The large-scale field is mapped using Cepheid-calibrated blue SNeIa. The local expansion field is mapped using Cepheids, a complete sample of TF distances, and nearby cluster distances. ![]()
