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:
