Using game-theory to look for extraterrestrial intelligence

Posted by in category: alien life

Astronomer Eamonn Kerins with the University of Manchester has developed an approach to looking for intelligent extraterrestrial beings on other planets that involves using game theory. He has written a paper describing his ideas and has uploaded it to the arXiv preprint server.

The current approach to looking for on other planets is basically two-pronged. One approach involves scanning the skies looking for signals from space that could be created by intelligent beings. The other involves scanning the sky for evidence of exoplanets that appear to be habitable. Kerins suggests that a way to meld the two approaches into a logical systematic search for is to use some of the logic inherent in game theory.

Kerins starts by noting that it seems possible that the reason scientists on Earth have not discovered signals from beings on other planets is because they are not sending any, fearing that doing so might draw the attention of unfriendly adversaries. He further suggests that if others are out there, they might be listening just as intently as we are. This leads to the SETI paradox, in which everyone is listening but no one is sending. And it also leads to the question of how such a paradox could be resolved. He notes that suggests that both parties should agree that the party with more access to information should be the one that transmits first to the other.

    I like this game very much. He further suggests that if others are out there, they might be listening just as intently as we are. both parties should agree that the party with more access to information should be the one that transmits first to the other.
