In a time machine, we explore what would happen if the past could be altered. We travel to the planets of other stars. We retrace the teen-age Albert Einstein's reverie about traveling on a beam of light; his theory of relativity predicts strange effects that arise from travel near the speed of light. [Volume] IX : A discussion of the building blocks of matter--molecules, atoms, subatomic particles--leads to an explanation of the anatomy of stars and the forces that act on stellar interiors. Stellar evolution, supernovae, and neutron stars are all dealt with. An "Alice in Wonderland" sequence is used as a playful point of reference to explain gravitational effects, from earth gravity to black holes.
