MESSAGE TO AN INTELLIGENT CIVILISATION : A HISTORICAL PERSPECTIVE

摘要

METI stands for Messaging to Extraterrestrial Intelligence. The idea of sending messages to other worlds is older than SETI (Search for Extraterrestrial Intelligence). However, the first real attempt of transmission was performed after the first SETI experiment. This paper retraces the notion of life on other worlds, from the Greeks to present day. It explores the many proposals to attempt communication with the inhabitants of those worlds and also the real experiments.
