OK, this is a slip up I think in the plot. The whole story revolves around the triangle that sets off a control in time when the nine planets in the Solar System are aligned. How in the world did the ancients know that there was a Solar System? or nine planets? Or that the planets revolved around the sun? If I read my History books right, people back then thought the whole universe revolved around the Earth. It took Galileo to figure that out. And Pluto and the rest of the nine planets wasn't discovered for a long time after. I know it's picky, but shouldn't the producers read up on stuff like that before?
