I'm currently finishing up The Fabric of the Cosmos, in which a surprisingly large number of head-crunching cosmological theories are discussed in a lighthearted tone with small words and pretty pictures*. The latest disturbing thing I've run across in the book (well, I think... see the footnote below) is that, entropically speaking at least, black holes have a surface.

No, don't ask me to explain it, because I'll just sound even dumber than I already do (oh be quiet, I can too! ... Waitaminute...) Anyway now it would appear not only do they have a surface, they're also a liquid. At least in ten dimensions. I think. Gah... I'm going to go soak my head now...

* I'm an anthropology graduate specifically because I'm horrible at math. Horrible. Yet, in one of those great karmic ironies, I'm also fascinated with physics and astronomy. So, how to explain the universe's inner workings to someone with (in this field) a comprehension level slightly below that of a kumqwat? Lighthearted sentences, pretty pictures, and small words. Even then I've had to set the thing down and walk away a few times feeling like someone had just hit me over the head with bag of buckshot.
