Extraterrestrial Intelligence refers to the hypothetical existence of intelligent life forms beyond Earth. Scientists and researchers explore this concept through various fields, including astronomy and astrophysics, seeking evidence of life on other planets. The search often involves analyzing signals from space and studying extreme environments on Earth where life thrives. The Search for Extraterrestrial Intelligence (SETI) is a prominent initiative aimed at detecting signs of intelligent life in the universe. This involves using powerful telescopes to listen for radio signals or other forms of communication that could indicate the presence of alien civilizations. The quest for understanding our place in the cosmos continues to inspire both scientific inquiry and popular culture.
