Is Messaging Aliens a Bad Idea?
Cool Worlds・2 minutes read
Modern SETI began in 1960 with Frank Drake listening for radio signals from distant stars, leading to the creation of METI in 1974; the debate around the risks and benefits of broadcasting messages to potential extraterrestrial civilizations continues. Game theory is applied to analyze the strategies in the METI debate, focusing on the balance between existence value and contact value, as well as the probabilities of reply and annihilation in potential interactions with alien societies.
Insights
- Frank Drake pioneered modern SETI in 1960, shifting from listening to broadcasting in 1974 to create METI, sparking controversy and calls for caution in messaging extraterrestrial civilizations.
- Game theory is applied to analyze the METI debate, focusing on the balance between existence value, contact value, reply probability, and annihilation probability, determining conditions for the success of METI proponents and exploring scenarios where declining civilizations may engage in METI for legacy purposes.
