http://www.nasa.gov/home/hqnews/2006/aug/HQ_06297_CHANDRA_Dark_Matter.html Well, dark matter at any rate. But isn't black materia made of Dark Matter?
At any rate, this is REALLY f'n important to us, it's one more thing that prooves Einstien correct (again) and makes all those tinfoil hat weirdos with alternate theories about why gravity works the way it does look like the idiots they are. Now we just need some good physical proof of gravitons and I'll be happy. I seriously didn't think we'd be able to directly prove the existance of Dark Matter in my lifetime.
I really don't know what else to say about Dark Matter. It's dark, it's matter, and it's totally bitchin'.
