Abstract
The standard model of modern cosmology might be cracked by the recent persistent hot debate on the Hubble-constant (H0) tension, which manifests itself as the sound-horizon (rs) tension or absolute-magnitude (MB) tension if deeming the origin of the Hubble tension from modifying the early or late Universe, respectively. In this study, we achieve a fully model-independent constraint (fitting a model-independent global parameterization to a model-independent inverse distant ladder with a model-independent high-redshift calibration) on late-time models with strong evidence against homogeneous new physics over the Λ-cold-dark-matter (ΛCDM) model. Further using this model-independent constraint to calibrate sufficiently local supernovae with corresponding late-time models extrapolated below the homogeneity scale, we find surprisingly that, although both H0 tension and MB tension are absent in our local Universe, a combination of H0 and MB as the intercept aB of the magnitude-redshift relation exhibits 3 ∼ 7σ tension even for the ΛCDM model. This aB tension seems to call for local-scale inhomogeneous new physics disguised as local observational systematics.
