In the past decade, an intriguing and persistent discrepancy referred to as the "Hubble tension" 7 has been apparent at high significance (>5σ) between the Hubble constant (H0) directly measured from redshifts and distances, which are independent of cosmological models, and the same parameter derived from the ΛCDM model calibrated in the early Universe (for a recent review, see Verde et al. 2023). The most significant disparity arises from the strongest constraints.
