METI International

METI targets nearby stars and researches the nature of the messages to send.^[1][8] On October 16, 17, and 18, 2017, it sent a message consisting of a scientific and mathematical tutorial to the red dwarf Luyten's Star, just over 12 light years from Earth.^[9][10][11] The message was sent from a radio transmitter at the EISCAT research facility in Tromsø, Norway.^[12]

METI's aim is to build an interdisciplinary community to design interstellar messages, within the context of the evolution of intelligence and language.^[13] In May 2016, it convened the meeting “The Intelligence Of SETI: Cognition And Communication In Extraterrestrial Intelligence” in Puerto Rico.^[2][4] In May 2018 in Los Angeles, it held “Language in the Cosmos” in conjunction with the International Space Development Conference.^[13][14] to examine the connection between astrobiology and linguistics.^[8] On March 22, 2017, it held a workshop in Paris examining the question "What is life?" from an extraterrestrial perspective.^[15]

METI also conducts an optical search of extraterrestrial intelligence (SETI).^[16][2] Its optical observatory in Panama looks for laser pulses from advanced civilizations. It has examined anomalous stars like the nearby red dwarf star Ross 128,^[17] as well as HD 164595, 94 light years from Earth.^[16] None of the searches has yielded evidence of artificial signals.^[16][17]

American scientist and science-fiction author David Brin has questioned "whether small groups of zealots should bypass all institutions, peer critique, risk appraisal or public opinion, to shout ‘yoohoo’ into a potentially hazardous cosmos" and so force a fait accompli on humanity.^[18]

Numerous other authors and scientists have expressed similar concerns, generally known as the Dark forest hypothesis of ETI, including Stephen Hawking.^[19][20] Of particular interest in science fiction is Cixin Liu's Remembrance of Earth's Past, exploring the theory and some of its implications.^[21][22]
