Replying late, but I finally got a chance to read your blog, Joe. I posted comments, which are also below. Great information as always, Joe. Thanks for the work you do to convey concepts such as this to dummies like me. I especially appreciate the work you put into providing historical background. It will be interesting to see how much of an impact this wrinkle will have for our estimates of the size and age of the universe. While somewhat dated now, Dennis Overbye's book "Lonely Hearts of the Cosmos" (1991) includes an excellent account of the importance of using Cepheid variables as "standard candles" as a starting point for these estimates. I'm sure there are more up-to-date narratives available, but I'm not familiar with them. Thanks again.
