It beings with Edmond Halley, a 16th (sixteenth) century scientist and colleague of Newt, directly addressing the camera as he talks about Newton’s law. A WS of a rocket launching. A diagram on a dot, representing a satellite, moving around the earth in orbit. A CU of a Newton’s Cradle. A dimly lit shot of a ball scattering a group of other balls. A CU of a giant modern telescope. A dim shot of the sun.
