Brian Cox considers the nature of time. He explores the cycles of time that define the lives of humans on Earth, and compares them to the cycles of time on a cosmic scale.
The final episode shows how the unique properties of light provide an insight into the origins and development of mankind and the Universe.
Ideas about time and space are explored in the changes that constellations undergo over time, the redshift and blue shift measured in interstellar objects, time dilation in Albert Einstein's theory of relativity, the designs of both Leonardo da Vinci and spacecraft that could travel near light speed, time travel and its hypothetical effects on human history, the origins of the Solar System, the history of life, and the immensity of space. In Cosmos Update, the idea of faster-than-light travel by wormholes (researched by Kip Thorne and shown in Sagan’s novel Contact) is discussed.
