“[W]hat Fermi immediately realized was that the aliens have had more than enough time to pepper the Galaxy with their presence. But looking around, he didn’t see any clear indication that they’re out and about. This prompted Fermi to ask what was (to him) an obvious question: ‘where is everybody?’” –Seth Shostak
When you consider that there are definitely millions of planets in the habitable zones of their stars within our Milky Way galaxy alone, the possibility that there’s intelligent life on at least one of them, right now, is tantalizing. But we’re in our technological infancy, relatively speaking, having only been broadcasting electromagnetic signatures visible by an alien civilization for around 80 years.

Unsurprisingly, we’re looking for exactly the types of signals we’re capable of sending, but what if that’s totally wrongheaded? Based on how technology is evolving and what the Universe is capable of, perhaps we should be looking not at electromagnetic radiation, but some other signals from the distant Universe to search for alien civilizations?
