Finding bundle

The tension between Planck (67.4 km/s/Mpc) and SH0ES (73.2 km/s/Mpc) measurements reaches approximately 5σ statistical significance, with the observed discrepancy magnitude of ~5.8 km/s/Mpc.

Finding 5 cites 5σ Planck-SH0ES tension; Finding 8 shows DESI-SH0ES tension is only 3.4σ, indicating the tension magnitude is not uniform across measurement classes

incoming

The SH0ES team's local distance ladder measurement of the Hubble constant yields H0 = 73.2 ± 1.0 km/s/Mpc (2024 update), using Cepheid variables in host galaxies of Type Ia supernovae observed with the Hubble Space Telescope.
supports · vf_31f784d57b86dd10
The statistical significance of the Hubble tension has been characterized as robust across jackknife resampling tests, with systematic exclusion of individual datasets showing the tension is not driven by any single measurement but is distributed across multiple sources.
