An invisible substance that is known to exist because we can see it's gravitational effect on stars (in effect, it's the 'glue' that keeps starts rotating together in Galaxies).
See wiki (link below) for a better description :-)

The universe we see is only 5% of all it is. Dark Matter is about another 35% of it. Dark energy is what compromises the other 60% of everything. In the New Scientist there is a map of universal dark matter. Gordon Bennet!

We have no idea. Theorists have lots of off-the-wall theories, but the particle physics and astrophysics communities haven't really gotten behind one.
We think it's there, though, because we can see how fast the universe is expanding and figure out from that how much mass it needs to have. The mass we can see is a small fraction of that mass, so there's missing energy/matter somewhere. Damned if we can find it though.
