Galactic whirlpools

Abstract

Interstellar gas rotates around the centre of the Galaxy more quickly than it ought to. Astronomers believe that this is caused by the gravity of dark matter; but Daedalus thinks it may be viscous drag, with the rapidly spinning central regions speeding up the outer parts, just like the water going down a plughole (the plughole in this case being the central black hole). He proposes that astronomers look for the gurgling noise that must be produced.
