The latest distance ladder measurements have inferred a value of the Hubble factor inconsistent at ~4\sigma with the value that best fits the data from the PLANCK experiment. To ease the tension, an anomalous expansion of the universe due to early dark energy has been posited. A Pseudo Nambu-Goldstone boson, which begins oscillations at matter-radiation equality, is consistent with...
