Communication with Extraterrestrial Intelligence

Communication with Extraterrestrial Intelligence involves sending and receiving messages across space to detect or establish contact with intelligent life beyond Earth. It relies on radio waves or other signals that travel vast distances at light speed. Scientists use powerful telescopes and mathematical algorithms to search for signs of alien signals or to transmit messages, often focusing on specific star systems. The process requires overcoming challenges like vast distances, signal degradation, and uncertainties about alien perceptions. Ultimately, it aims to answer whether we are alone in the universe and to potentially share knowledge with other intelligent civilizations.
