Artificial Intelligence Will Let Humanity Talk to Alien Civilizations
Large language models may enable real-time communication with extraterrestrial civilizations despite the vast distances between stars. We need to start thinking about what to tell them about us

Artificial intelligence mania has overtaken our economy and will soon expand beyond Earth to become omnipresent in spacecraft as well. It’s worth asking, what does this mean for the search for extraterrestrial intelligence? Just like on Earth, AI promises a rethinking of long-cherished hopes for space exploration, such as finding that we are not alone in the universe.
AI’s advances explain this ambition. Introduced in 2017, the “transformer” neural network architecture has become the cornerstone of today’s large language models (LLMs). Trained on Internet-scale datasets, these models contain vast human knowledge and are changing our world. They will affect nearly 40 percent of global employment, according to the International Monetary Fund (IMF).
Could this technology help us communicate with hypothetical advanced civilizations elsewhere? SETI, the search for extraterrestrial intelligence, has been around as long as METI, messaging extraterrestrial intelligence, the aim of which is to attempt to find and communicate with extraterrestrial civilizations. But after 40 years of serious search we have not found such ET intelligence, and our messages remain unanswered. We cannot conclude that we are alone in the galaxy, given its vastness and our nascent search efforts. It may be time to radically rethink our approach, however.
As alien-curious scientists, we propose advancing METI by transmitting not just music, math or brief descriptions of ourselves but something more meaningful: a well-curated large language model that encapsulates the diverse essence of humanity and the world we live in. This would enable extraterrestrial civilizations to indirectly converse with us and learn about us without being hindered by the vast distances of space and its corresponding human lifetime delays in communication. Aliens could learn one of our languages, ask the LLM questions about us and receive replies that are representative of humanity.
This is a radical and potentially risky idea because unfriendly aliens could misuse this information. Nevertheless, it’s a discussion worth starting, given recent discoveries. Space telescopes such as Kepler and the Transiting Exoplanet Survey Satellite (TESS) have revealed that our galaxy is full of exoplanets, and it’s estimated that at least 300 million are similar to Earth and potentially harbor liquid water. We believe that several of these worlds could host technological civilizations curious to meet us and learn about us.
