The story goes that, on a very dark night, a group of stars began to fall. They fell in parallel, weaving among one another and dancing together.
Those stars were so closely bound that whenever one of them accelerated, the others followed along, for they were all magnets to one another.
Sometimes it was one; sometimes another. The dance went on, and their impulses grew stronger. The faster they danced, the sooner they landed.
How could the star Cassiopeia fail to see what was happening, when she danced and danced just like the rest?
