Editor’s note: I’ve just deleted the most widely shared post on The Nag, along with its hundreds of associated reader comments. They’ve all been removed from this site out of an abundance of caution (and a wee sigh of despair) because this particular article has, sadly, been adopted as the darling of the anti-science movement – never my intention, even when I was pointing out challenging problems or asking difficult questions. As Dr. Frederick Seitz once observed:
“Once a scientist gets an answer, there are always more questions.” .
