Hubble Tension – The Plot Thickens

One topic on this blog seems to be as perennial as the weeds in my garden: the so-called Hubble Tension. I just saw a review paper by Wendy Freedman, one of the acknowedged experts in this area, on arXiv here. I have abstracted the abstract here:

You can find the PDF here.

What’s particularly interesting about this discussion is that stellar distance indicators have typically produced higher values than the 69.8 ± 0.6 (stat) ± 1.6 (sys) km s^-1 Mpc^-1 quoted here, which is consistent with the lower value favoured by Planck. See the above graphic discussed here. So perhaps there’s no tension at all. Maybe.

Anyway, here’s that poll again! I wonder if this paper might change the voting.
