That's a cool graph. It's hard to see, but it looks like we can't say it is distinguishable from zero?



Zero is the very bottom of the graph. The consensus value is somewhere between 50 - 100.


Interestingly, there was a long fight in the field of cosmology from ~1960 until ~1990 as to whether the Hubble constant was 50 or 100. It wasn't until within the past twenty years or so that the community began to agree upon the now-accepted value of ~70 km/s/Mpc.
