Scenarios about 'SETI'
The Search for Extraterrestrial Intelligence (SETI) comprises scientific efforts to detect evidence of technologically advanced civilizations beyond Earth. Since the mid-20th century, SETI programs have employed radio telescopes and other technologies to scan for artificial signals from distant star systems, reflecting humanity's enduring questions about our cosmic uniqueness. In alternate history scenarios, SETI often serves as a pivotal element in timelines where first contact occurs or where different technological priorities alter humanity's approach to space exploration.
