Well, they’re black, and they’re like bottomless holes. What would you call them? -Me, when a friend asked me why they’re named what they are

Ah, black holes. The ultimate shiver-inducer of the cosmos, out-jawing sharks, out-ooking spiders, out-scaring … um, something scary. But we’re fascinated by ’em, have no doubt — even if we don’t understand a whole lot about them.

But then, that’s why I’m here. Allow me to be your tour guide to infinity. Or the inverse of it, I suppose. Since it’s Halloween this seems appropriate … and my book Death from the Skies! just came out, and there’s lots of ways a black hole can destroy the Earth. Mwuhahahaha.

So below I present ten facts about black holes — the third in my series of Ten Things You Don’t Know (the first was on the Milky Way; the second about the Earth). Regular readers will know a few of these since I’ve talked about them before, but I’m hoping you don’t know all of these. And if you do, then feel free to leave a comment preening about your superior intellect. Mind you, this list is nowhere near complete: I could have picked probably 50 things that are weird about black holes. But I like these.
