"That was a great metaphor for me because I was interested in the idea that one of the ways that astronomers were looking for other planetary systems was to look out into space, and they oftentimes could not see the star that was the center of the solar system, but they could see a planet, or some bit of a planet, that was orbiting around something and was being influenced gravitationally by something bigger than itself that the astronomer couldn't see."
