The science fiction movie "Arrival," which opened in theaters this month, poses tantalizing questions about how humans might make contact — and eventually communicate — with intelligent aliens. The much-hyped film has renewed people's interest in the search for intelligent life elsewhere in the universe. But what would happen if humans really did make contact with an intelligent alien civilization? If E.T. calls, is there a plan?
The answer is yes, and no, said astronomer Seth Shostak, who leads efforts to detect radio signals from extraterrestrial civilizations at the SETI Institute in Mountain View, California.
"There are some protocols, but I think that's an unfortunate name, and it makes them sound more important than they are," Shostak told Live Science.
In the 1990s, Shostak chaired a committee of the International Academy of Astronautics (IAA) that prepared a revised version of the "post-detection protocols" for researchers who watch for possible alien transmissions using radio telescopes, a field known as SETI (short for the Search for Extraterrestrial Intelligence).
The protocols were first drawn up in the 1980s to help scientists in the United States and the Soviet Union share information about any potential SETI signals. But, Shostak explained, the SETI post-detection protocols are guidelines for governments and scientists, rather than a global action plan for dealing with alien contact.
