Synopsis by Alice Day
Is time travel possible? Are there other planets in their own solar systems? Why do star patterns change? These questions are addressed in this installment of the highly acclaimed PBS series Cosmos, written and hosted by astronomer/author Dr. Carl Sagan. Through the magic of special effects, the viewer goes on a journey to observe the evolution of stars over millions of years, then sees a simulation of other stars with their orbiting planets. In Cosmos, Episode 8: Travels in Space and Time, Dr. Sagan also travels to Italy and introduces the young Einstein as he ponders beams of light and their speed.
