The Edge of Forever
Dr. Sagan leads us on some awesome trips — to a time when galaxies were beginning to form, to India to explore the infinite cycles of Hindu cosmology, and to show how humans of this century discovered the expanding universe and its origin in the big bang. He disappears down a black hole and reappears in New Mexico to show us an array of 17 telescopes probing the farthest reaches of space.
