Alien communication refers to the hypothetical ways in which extraterrestrial beings might convey information to one another or to humans. Scientists explore various methods, such as radio signals, light patterns, and even chemical signals, to understand how intelligent life forms might share messages across vast distances in space. Researchers, including those at SETI (Search for Extraterrestrial Intelligence), use advanced technology to listen for unusual signals from space. They analyze these signals for patterns that could indicate intelligent origins, hoping to establish contact with potential alien civilizations and learn about their languages and cultures.
