If both sets of $H_0$ measurements are accurate, what is the implication for the standard cosmological model ($\Lambda$CDM)?

Answer

That the standard model is incomplete, suggesting unknown physics influenced expansion between the CMB time and today.

If the measurements disagree and both are flawless, it suggests that the standard cosmological model ($\Lambda$CDM) lacks necessary components, implying that unknown physics related to dark energy, dark matter, or new particles affected the expansion rate unexpectedly over cosmic time.
