This episode documents how gravity has an effect across the universe, and how the relatively weak force creates an orbit. We also see how a neutron star's gravity works. Finally, there is a look back at how research on gravity has enabled us to better understand the cosmos.

The Ship of the Imagination embarks on a journey through space and time to grasp how the autobiography of the Earth is written in its atoms, its oceans, its continents and all living things. Later, American geologist Marie Tharp creates the first true map of Earth's ocean floor, and discovers microscopic life that exists deep beneath the ocean.

The first of the two-part series, titled "From Space," explores the birth and early life of Earth, as seen from orbit, using clues from over 300 satellites and space stations surveying Earth’s landmarks to work backwards and piece together what the planet’s early days might have looked like.

Sagan discusses the story of the Heike crab and artificial selection of crabs resembling samurai warriors, as an opening into a larger discussion of evolution through natural selection (and the pitfalls of intelligent design). Among the topics are the development of life on the Cosmic Calendar and the Cambrian explosion; the function of DNA in growth; genetic replication, repairs, and mutation; the common biochemistry of terrestrial organisms; the creation of the molecules of life in the Miller-Urey experiment; and speculation on alien life (such as life in Jupiter's clouds). In the Cosmos Update ten years later, Sagan remarks on RNA also controlling chemical reactions and reproducing itself and the different roles of comets (potentially carrying organic molecules or causing the Cretaceous–Paleogene extinction event).
