TY  - JOUR
AB  - The Hubble constant ($H_0$) estimated from the local Cepheid-supernova (SN)distance ladder is in 3-$\sigma$ tension with the value extrapolated fromcosmic microwave background (CMB) data assuming the standard cosmologicalmodel. Whether this tension represents new physics or systematic effects is thesubject of intense debate. Here, we investigate how new, independent $H_0$estimates can arbitrate this tension, assessing whether the measurements areconsistent with being derived from the same model using the posteriorpredictive distribution (PPD). We show that, with existing data, the inversedistance ladder formed from BOSS baryon acoustic oscillation measurements andthe Pantheon SN sample yields an $H_0$ posterior near-identical to the PlanckCMB measurement. The observed local distance ladder value is a very unlikelydraw from the resulting PPD. Turning to the future, we find that a sample of$\sim50$ binary neutron star "standard sirens" (detectable within the nextdecade) will be able to adjudicate between the local and CMB estimates.
