The Controversy and Risks of Messaging Extraterrestrial Intelligence
TLDR The controversy surrounding actively sending messages to extraterrestrial intelligence is based on the belief that we may be alone in the universe, while others argue that intentional transmissions could attract harmful attention. The scientific community is divided on the ethics and risks, with some arguing for international regulations and others believing the potential benefits outweigh the risks.

This podcast episode discusses the concept of Medi, also known as Active Setti, which involves actively sending messages to extraterrestrial intelligence rather than just passively listening for alien transmissions.

The controversy surrounding the concept of actively sending messages to extraterrestrial intelligence is based on the belief that the lack of contact with alien civilizations thus far suggests that we may be alone in the universe, while others argue that it is too soon to draw that conclusion and that intentional transmissions could potentially attract harmful attention from unknown entities.

In the early 19th century, there were various proposals on how to send messages to extraterrestrial intelligence, including planting wheat fields in the shape of right triangles and setting large trenches on fire, but the first official METI broadcast occurred in 1962 when Soviet astronomers sent a three-word message in Morse code to a star 2,000 light years away.

Binary code is often considered a universal language and is commonly used in crafting messages for potential extraterrestrial contact.
19:57
There have been solo attempts by individuals, often for artistic or commercial reasons, to send interstellar messages, such as Joe Davis who transmitted the vaginal contractions of ballet dancers and the genetic code for a plant enzyme essential for photosynthesis.
25:04
The scientific community is deeply divided and heatedly debates the ethics and risks of messaging extraterrestrial civilizations, with some scientists leaving their groups over the issue, while organizations like METI and NASA's Jet Propulsion Laboratory have sent messages to exoplanets in hopes of receiving a response.
30:00
The scientific community is divided on the ethics and risks of messaging extraterrestrial civilizations, with some arguing that it is not a good idea and that it poses an existential threat, while others believe that it is worth pursuing and that the potential benefits outweigh the risks.
34:55
There should be international laws and regulations around messaging extraterrestrial civilizations, and those who violate these regulations should be prosecuted, according to a position statement signed by a group of scientists in the 2000s.
39:43
The argument that our radio and TV transmissions are a danger because they could attract hostile extraterrestrial civilizations is not valid, as these transmissions are so degraded by the time they reach space that they would be nearly impossible to pick up, and the chances of an alien civilization being able to detect and understand them are extremely small.
44:51
The argument that alien civilizations might have developed altruism for their own society but not extended it to other societies, and therefore might see a need to wipe out up-and-coming societies like ours, is a valid concern in the debate about whether or not to make contact with extraterrestrial civilizations.
