Cosmologist Paul Davies from NAI’s ASU team, winner of the 1995 Templeton Prize, believes that SETI’s search for narrow-band radio signals from planets around other stars needs to be broadened to look for other possible signs of life. In his new book, The Eerie Silence: Renewing Our Search for Alien Intelligence, he explores the idea that aliens may be using far more advanced technology than radio to signal the cosmos, such as manipulating pulsars to act as beacons or even neutrino signaling. Davies also puts forth the possibility that alien probes may be silently trolling the solar system. The author surveys popular topics in science fiction such as Dyson spheres, time travel, and wormholes, and decides that they’re not feasible under physics as we understand it. He concludes with a far-ranging look at what might happen here on Earth when we make first contact.
