Abraham Loeb and Shmuel Bialy kicked up a kerfuffle when they wrote a paper suggesting that one possible explanation for ‘Oumuamua was that it could be an artificial object, in other words, an alien spacecraft—specifically, a lightsail. The two have been praised for their boldness and condemned for their recklessness, but little has been said concerning the possibility of detecting a lightsail as a technosignature in comparison to detecting a “conventional” technosignature such as the radio and laser beacons that SETI searches for. When we look out into the universe for signs of intelligence, if there are technosignatures to be seen, what technologies ought we to expect to be the most common?
