Science DiscoveriesIf you were seeking for alien intelligence, looking for a convincing signature of their activities from across the Universe, you’d have a few alternatives. You may look for sentient radio broadcasts, similar to the ones humans began emitting in the twentieth century. You could check for artificial lighting at night, such as what our cities and towns have visible from space. Alternatively, you may hope for a technological breakthrough, such as the generation of particles such as antineutrinos in a nuclear reactor.
