A Ham Radio operator’s take on the Fermi Paradox
The Fermi paradox, in one line: a galaxy of hundreds of billions of stars, most of them billions of years older than the Sun, should be full of civilizations, so where is everybody? After 65 years of listening for carriers near 1420 MHz — Ozma, SETI@home, Breakthrough Listen — the band is still dead. A new hypothesis, called Behavioral SETI, asks whether the silence is a design feature: instead of listening for a transmitter, it has run 49 searches of public astrophysics archives for a network that signals by modulating sources already on the air — leaving the demodulation to us.
