CARL SAGAN
The Possibility of Life in the Universe
This lecture by Carl Sagan was delivered one early evening in September 1974 (most likely Thursday, 5 September) to the U.S. Air Force Academy at Arnold Hall theater in front of a 3,000 cadet packed house lecture. It reflects the science of that time, and in the Q&A Dr. Sagan addresses the related claim that not only is there definitive proof for the existence of Extra-Terrestrial Intelligence in the cosmos, ETIs have visited Earth. Dr. Sagan’s exquisite deconstruction of such claims is a classic exercise in skeptical and critical thinking. He received a lengthy standing ovation.
