Who died and made this article God?
Nobody. We're discussing the article here.
As for the relatively recent evidence of dark matter showing its imprint in the CMB, well, again, doesn't this support my thesis that this is a rapidly evolving field? Cosmology textbooks have a short shelf life. Thirty years ago, for example, one of the big questions was whether the universe was open or closed. Now that we know it's open, and in fact expanding at an accelerating rate, we find that wasn't quite the right question. My physics textbooks, by contrast, are still readable. If a science gets dated quickly, then isn't that reason to think it's speculative?
