Y'know what would be interesting, what would happen if the Discworld came into contact with a miniature black hole? There's short stories about the same thing happening to Mars or Earth, but it gets whole new implications with the Disc. The pinhole left by a mini black hole would be smaller in relation to A'Tuin than something half a molecule wide would be to a normal turtle; would he even notice? Long term, it would orbit the Disc's center of gravity and gradually suck up all the matter over millennia. Where is the disc's center of gravity anyway? Surely A'Tuin is more massive than the Disc itself, and who knows the exact volume and density of the elephants...perhaps it would just end up orbiting in space between the elephants and do nothing at all. If something ended up punching a hole through the Disc somewhere in the middle, would all the air fall out? What if Cori Celesti was an inverted massive impact crater like that mountain in Ringworld? There's all sorts of interesting possibilities here...
