The Last Resting Place of the Hubble Parameter?

Posted in Uncategorized with tags , , , on July 22, 2019 by telescoper

Last week was rather busy on the blog, with a run of posts about the Hubble constant (or, more precisely, the  present value of the Hubble parameter) attracting the most traffic. Somehow during all the excitement I allowed myself to be persuaded to write a piece for RTÉ Brainstorm about this issue. My brief is to write a detailed account of the current controversy in language accessible to a lay reader in not more than 800 words. That’s quite a challenge. Better get on with it.

Perhaps after that I’ll be able to lay the Hubble parameter to rest, at least for a while:

Death of a Cosmological Parameter

I’m sad to have to use the medium of this blog to report the tragic death of the Hubble parameter. It had been declining for some time and, despite appearing to pick up recently, the end was somewhat inevitable. Condolences to the other parameters, especially Ω (who was in a close relationship with H), on this sad loss.
