Planck measurements of the cosmic microwave background power spectra find a lower value of the Hubble constant H₀ and a higher value of the fractional matter energy density Ω_m0 for the concordance ΛCDM model, and these results are in tension with other measurements. The Planck group argued that the tension came either from so…
