Kinda cool.

Scientists unveil biggest ever map of universe's dark matter - CSMonitor.com

Dark matter is the weirdest stuff. It's one of the reasons galaxies hang together. When I was in college, there was no mention of dark matter. Anyway, it acts like gravity.

Black holes are another thing altogether. It's usually a collapsed star or groups of stars.

That's the quick answer, anyway.
