A closer look at “A Brief History of METI: Early Attempts to Message Extraterrestrial Intelligence | Nova Gl”, exactly as the source publishes it. For centuries, humanity has gazed at the stars, wondering if we are alone. This enduring question—often called the 'Great Silence'—has fueled both science and imagination. The search for extraterrestrial intelligence, or SETI, has primarily focused on listening for signals from other civilizations. This enduring question—often called the 'Great Silence'—has fueled both science and imagination.
However, a more proactive approach, known as Messaging Extraterrestrial Intelligence (METI), involves transmitting deliberate signals into space in the hope of making contact. The history of METI is rooted in early theoretical ideas and experimental efforts that emerged alongside the space age. Pioneering scientists and thinkers, including figures like Frank Drake and Carl Sagan, played key roles in shaping the debate over whether we should announce our presence to the cosmos.
