Summary
Mar. 5, 2025
Dr. Simon Steel (SETI Institute)
Dr. Steel discusses the Copernican revolution and how it changed humanity's view of its place in the universe. He then talked about other "Copernican" discoveries that displaced us from a central perch, including the revision of our place in the Galaxy, the discovery of other galaxies, and now our finding a remarkable number of planets (including Earth-like planets) orbiting other stars. He explains how such discoveries give context for, and have prepared us for, the next potential Copernican revolution, the discover of intelligent life elsewhere in the cosmos. He concludes by describing some of the most exciting experiments now underway to find evidence of such life among the nearest stars and busiest galaxies. Dr. Steel is Deputy Director of the Carl Sagan Center for Research at the SETI Institute.
