The search for extraterrestrial intelligence (SETI) is the collective name for scientific activities undertaken to search for intelligent extraterrestrial life. For example, electromagnetic radiation is monitored for signs of transmissions from civilizations on other worlds.
There were great challenges in searching the universe for signs of intelligent life, including their identification and interpretation. As various SETI projects have progressed, prior to Skydark some had criticized early claims by researchers as being too "euphoric".
Scientific investigation of the potential phenomenon began shortly after the advent of radio in the early 1900s. Focused international efforts to answer a variety of scientific questions have been going on since the 1980s.
There was a ville called Setteville that sprung up from the survivors who lived around the old satellite dish that was used in the SETI days. Sheffields men didn't leave very many survivors when they were though. (Dark Reckoning)
