... I want to write a book. I want to tell the story astrophysics tells -- not how we came to know it or who made which discovery but the story itself...the beginning of time and space, the condensation of matter, and how that matter was processed into the stuff of which we, and even our dreams, are made. The story of simple rules and the even simpler objects they acted on and still act on and will act on, forever. ... Astrophysics is one of the most compelling arguments ever made. ...

The Moon orbits around the Earth. ... To keep the Moon moving in that circle--rather than wandering off--the Earth must exert a pull on the Moon, and Newton named that pulling force gravity . ... If it was the same force, then a connection would exist between the way objects fell and the motion of the Moon around Earth, that is, its distance and orbital period. ... Newton went further and proposed that gravity was a "universal" force, and that the Sun's gravity was what held planets in their orbits. ...
