As far as I know Dark Matter is just a theory. It says that galexies dont have enough matter to keep them from bursting apart so they think something else is holding them together. Newer studies suggest not.

Again, this theory is all about dark energy, not dark matter.

And yes... the idea of dark matter... with the speed that galaxies and galaxy clusters rotate and the visible matter in the galaxies, the gravitational pull isn't strong enough to stop them from flying out in to space. Dark matter creates extra, weakly-interactive, non-visible mass to explain it.

Personally... I think it's much more likely to be a missing constant in the gravitational equations which means they work on a small scale, but not on a big scale... just not sure what yet.
