It’s not so much that I expect to be the first to detect signals from ET. In fact, as I’ve often joked, I’d rather that you detect them first, because then I get to stay at home and smoke my pipe, while you get to cope with the demands of the media.
What are the odds? We’ve only been listening for a few decades, hoping to detect coherent signals of any sort rising above the cosmic background noise. If we ever do detect a “signal”, the civilization that sent it might not even be around. Listening searches might be confined to local areas of interest, such as the Orion Nebula (1500 light years). Mighty “sister galaxy” Andromeda, on the other hand, is some 2.5 million light years distant.
