  • "[Volume] VIII : With Carl Sagan we circle around the Big Dipper to see it from a new perspective. 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."
  • "In a "time machine" Dr. Sagan travels through constellations and explores what would happen if the past could be altered, and explains the fact that time slows down close to the speed of light."
  • "Computer animation places the constellations in space and explains the concept of a light year. Einstein's theory of relativity is introduced and his percepts of space and time are illustrated. The feasibility of interstellar travel is discussed with a brief history of ideas proposed for space travel. Time travel is touched upon and the resultant profound effects it would have on the course of history considered."@en
  • "Host Carl Sagan uses computer animation to show the positions of the constellations and to explain the concept of a light-year. Dr. Sagan also discusses Einstein's theory of relativity, and he describes the feasibility of interstellar travel."@en
