Galaxy Sans Dark Matter

ChromaticDragon writes "Astronomers have crunched some numbers on a galaxy to discover that its rotation can be fully explained by the gravity of the observable matter — in effect, this galaxy seems to lack dark matter. This shouldn't come as a total surprise given that one of the stronger observations of Dark Matter was the Bullet Cluster where supposedly a good deal of Dark Matter and good old fashion regular matter had separated."

Definitely an interesting idea. Dark matter always sort of bugged me. But if it doesn't really exist, that means we can't use gravitic weapons (a la Schlock Mercenary) to talk to dark matter aliens!
