Moon solves Hubble tension

"Using sedimentary and eclipse-based measurements of the lunar recession velocity, we derive a new local-Universe measurement of the Hubble constant (H0) from the recession rate of Earth's Moon. Taking into account the effects of tides, we find a value of H0 = 63.01 ± 1.79 km s−1 Mpc−1, which is in approximate agreement with the Planck space mission's measurement using the cosmic microwave background (CMB) and base ΛCDM. Our new measurement represents the first ever model-independent, single-step measurement of the Universe's current expansion rate. This is also the first major local Universe measurement of H0 which is below the measurement from Planck. Importantly, it is robust to the systematic errors that may be present in other H0 measurements using other cosmological probes such as type Ia supernovae, baryon acoustic oscillations, or lensed quasars. Our work provides key evidence towards the notion that the existing Hubble tension may indeed be a result systematic uncertainties in the local distance ladder."
