Re: Differences

FTFA, the CMB method relies on a host of assumptions, which may or may not hold true (although obvs they are believed to do so!). It might be interesting to investigate what variation(s) in the assumptions for CMB would allow the two measurements to match.

Wither that or, as you rightly put it, challenge the underlying assumption that the Hubble Constant is indeed a constant.
