The telescope listened to 70,000 stars — silence. All hundred million 'suspicious' signals turned out to be our own interference. If alien transmitters were powerful searchlights, we'd have spotted them. But no: only six stars out of a hundred thousand could have such a 'cosmic loudspeaker'. It seems the galactic airwaves are silent.
🎯 The total energy of all human radio broadcasts ever made is less than the power of a single strong transmitter sought by this telescope.
🎬 In the movie 'Contact,' radio telescopes pick up an extraterrestrial signal. The real search, so far, is more like an attempt to hear silence.
