Single Measurement Unlikely Solves Hubble Tension

A recent analysis summarized by Big Think finds that removing suspected outlier measurements does not eliminate the disagreement between local measurements of the Hubble constant and values inferred from the early universe. That makes it increasingly unlikely that the discrepancy is a single bad data point and raises the probability that either widespread systematics or new cosmological physics are needed. — If the Hubble tension is not a lone measurement error, scientists, funders and science communicators must treat it as a robust anomaly that could justify new experiments, model revisions, and public discussion about scientific uncertainty.
