Worry No More, The Hubble Tension is Relieved: A Truly Direct
  Measurement of the Hubble Constant from Mooniversal Expansion
  Using sedimentary and eclipse-based measurements of the lunar recession
velocity, we derive a new local-Universe measurement of the Hubble constant
($H_0$) from the recession rate of Earth's Moon. Taking into account the
effects of tides, we find a value of $H_{0}$ = 63.01 $\pm$ 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 $\Lambda$CDM.
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 $H_0$ which is below the measurement from
Planck. Importantly, it is robust to the systematic errors that may be present
in other $H_0$ 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 of systematic uncertainties in the local distance ladder.
