In September, 1959, two physicists at Cornell University, Philip Morrison and Giuseppe Cocconi, published a paper in the science journal Nature entitled “Searching for Interstellar Communications.”
The Telegraph used the anniversary as an opportunity to post a top ten list of sorts: “SETI at 50: 10 key moments in the search for extraterrestrial life.” It’s a nice history lesson.
Critics of SETI often cite this 50-year search without a peep from an interstellar neighbor as proof that Earthlings are alone and special. Is scientifically scanning the Universe–which is, you know, big–for half a century long enough to definitively claim our uniqueness?
What do you think?
