Mmmmm, no. That's not what a black hole is.

A black hole is essentially gravity gone mad. In fact, given the density of the matter within the singularity, a black hole may very well be the least vacuous thing in the universe.

I don't know why, but reading through the Guardian article made me think of Isaac Asimov's novel "Nightfall". I really must go reread that one. Was a great story.

Anyway, interesting discovery. It only really deepens the mystery of the "cold spot", but still interesting.

I suspect he means 'vacuum' as in 'vacuum cleaner', which is a decent analogy for black holes that gets thrown around from time to time. But yeah, its a bad word to use when a black hole quite definitely isn't a region of empty space (ie the literal meaning of the word vacuum)...

Okay. That's cool. I'm guessing the young universe, which is sometimes referred to as a plasma 'bath' of hot particles, had a bubble in it?

Let's not track down the god-baby that made that bubble, shall we? :p
