I just really think the guy is an idiot. I don't watch CNN and don't know Lemon. But here's a possible alternative explanation (hardly a defense): Wikipedia says he graduated with a degree in broadcast journalism. He probably didn't pay much attention to science in high school, and almost certainly wasn't required to take any science classes in college. So, he might not even understand science as simple as F=ma. In his defense I'd bet that if you surveyed the adult population, the majority couldn't tell you what F=ma means. The above is a long way of saying that most journalists aren't literate in science. And, we know that black holes are "sexy". Many books have been written about them. Many movies made that feature them as key plot points. So, why not ask about black holes as a possibility? It's as plausible an explanation as whatever it was that happened to that airplane in the Lost TV series of about 10 years ago. Having said all that, yeah, the guy is probably an idiot. As are quite a few TV journalists.
