I have been finishing up a book on the fine-tuning of the Universe and hopefully it will be published (and will become a really big best seller?? :) in 2015. But time to rebirth the blog, and what a better way to start that a gripe. There's been some chatter on the interweb about a recent story about the speed of light in a vacuum being slowed down.  Here's one .  Here's another.  Some of these squeak loudly about how the speed of light may not be "a constant", implying that something has gone horribly wrong with the Universe.
