Carl Sagan - Cosmos 13 - Who Speaks for Earth?

Through the use of special effects we retrace the 15-billion-year journey from the big bang to the present. We also hear the tragic story of the martyrdom of Hypatia, the woman scientist of ancient Alexandria.

To conclude, Dr. Sagan delivers a monologue on the responsibility of mankind not just to earth, but to the cosmos, the source of our being.
