| Mar 28, 2019 at 14:41 | comment | added | MadMax | The confliction is intensified according to the last word: arxiv.org/abs/1903.07603. "The difference between H0 measured locally and the value inferred from Planck CMB+LCDM is 6.6+/-1.5 km/s/Mpc or 4.4 sigma (P=99.999% for Gaussian errors) in significance, raising the discrepancy beyond a plausible level of chance. We summarize independent tests which show this discrepancy is not readily attributable to an error in any one source or measurement, increasing the odds that it results from a cosmological feature beyond LambdaCDM". | |

| Mar 21, 2019 at 14:46 | comment | added | T. Smith | Conflicting measurements because the method is slightly different, "Whereas traditional measurements of H0 with SNe Ia use a distance ladder of parallax and Cepheid variable stars, the inverse distance ladder relies on absolute distance measurements from the BAOs to calibrate the intrinsic magnitude of the SNe Ia." I'll too naive to know the significance of this - it seems to me as long as both methods are generally OK they should give the same values, but they do not. | |
