Significant Discrepancy Found in Hubble Constant Measurements

Recent analysis by Leandros Perivolaropoulos has highlighted a significant discrepancy in the measurements of the Hubble constant ($H_0$), a key parameter in cosmology. The study, titled 'Hubble Tension or Distance Ladder Crisis?' and available on Arxiv.org, presents a comprehensive compilation of $H_0$ measurements that are independent of the Cosmic Microwave Background (CMB) sound horizon scale.
