dark matter and black holes

My friend and I have been kind of on a science curve lately and I was wondering what is the connection between black holes and dark matter? (the more detailed the answer the better)

As far as we know, there's no fundamental relationship. Dark matter is the name for a kind of matter - most likely a new fundamental particle - which emits little or no light because it doesn't interact (strongly) using the electromagnetic force. It's almost certainly not made of black holes, observations constrain that very strongly.

Black holes are what happens when any kind of matter or energy is compressed into an area so small that, because of the speed of light limit, it can't hold out against gravity, and collapses to (nearly) a single point. Black holes *can* be formed from dark matter, although most of the dark matter in the Universe is moving so quickly that it never clumps into dense enough regions to form a black hole.
