A Course on Aliens in Science & Science Fiction for People Over 50

I am teaching a fun, 6-week, non-credit course on the search for intelligent life among the stars, offered (by zoom or in person) through the San Francisco State University Osher Lifelong Learning Institute, starting Sept. 30. It’s part of a program of courses for retired people, so if you are younger, perhaps you can pass this on to a retired person you know. The richly illustrated course does not require any science background, and is open to anyone. We will discuss exciting experiments now under way to search for “techno-signatures” — evidence of other civilizations out among the stars, in the form of radio messages (not necessariy meant for us) or waste heat from space industry. We’ll look at the most imaginative ideas from science fiction about who or what might be out there. And we’ll also explain some of the most famous “UFO” cases, including just what happened in Roswell, NM.
