I remember reading a while back about all this Dark Matter that was supposed to exist, but no one could prove it. It was looking increasingly unlikely that it didn't exist or if it did it was a much smaller amount than originally thought. Which in turn would screw up quite a lot of science :-D
Maybe this is the first step to proving that it does exist.
I'll try and dig out that article over the weekend, might've been in an issue of Focue, New Scientist or that other sciency journal Scientific American.
