Dark Matter is real apparently, and not just a theoretical placeholder.

A cosmic collision has supplied direct proof that dark matter really exists, astronomers say. The collision has allowed dark matter to be separated from ordinary matter, casting doubt on the idea that dark matter could just be an illusion due to a flaw in our understanding of gravity.

The pull of gravity from ordinary matter seems to be insufficient to hold spinning galaxies together, including our own. This and several other lines of evidence point to the existence of a mysterious form of invisible matter that exerts a gravitational influence on other matter and outweighs ordinary matter by a factor of about 6 to 1.

Hmm. That's pretty damn cool. More thoughts when I don't have to dash off to work.
