Michael Michaud, author of "Contact with Alien Civilizations: Our Hopes and Fears about Encountering Extraterrestrials," was our Space Show guest for this in-depth discussion regarding ET contact. We started our discussion by having Mr. Michaud provide us with a broad brush definition of SETI. From there, we jumped into the discussion about validating signals, what type of signals, and could we even recognize a signal as coming from an ET civilization assuming it was out of the ordinary from our perspective.
