Great Cosmic Nothingness

As I have said before, I simply do not know that much about Astrophysics, Astronomy, and all of that stuff. I can generally follow along up to a point, but beyond that, it is literally over my head (no pun intended).

The other day, scientists claimed to have discovered The Great Cosmic Nothingness - whatever the hell that means - a space where nothing exists, literally. No matter, no antimatter, just... nothing. Nothing, as Descartes might put it.

What does this mean? Are there any sorts of repercussions or possibilities or anything to conclude from this? I haven't the foggiest. But I figured I would include the link to the article in case some of you bright minds had missed it. I'm sure most of you can make more sense of it than I can!
