Lecture 40: SETI - The Search for Extra-Terrestrial Intelligence
Is anybody out there? This lecture reviews the ideas behind SETI, the
Search for Extra-Terrestrial Intelligence, an effort to find other
intelligent communicating civilizations by tuning in on their radio or
other electromagnetic communications. I will discuss the basic
approaches being taken by various SETI efforts, and what we expect to
find. In addition to listening, we have also been broadcasting,
intentionally or otherwise, messages into space, and we have sent
physical artifacts with descriptions of our home on robotic spacecraft
headed out of our solar system into interstellar space. Recorded live
on 2009 Nov 24 in Room 1005 Smith Laboratory on the Columbus campus of
The Ohio State University.
