The Fermi Paradox: The Universe Is Quiet Because Civilizations Meet the Great Filter
In 1950, during a lunch at Los Alamos, physicist Enrico Fermi discussed the possibility of life beyond Earth and asked his colleagues, “Where is everybody?” The short question became the Fermi paradox. The Milky Way has hundreds of billions of stars; many are billions of years older than the Sun and have planets. If even a tiny fraction produce intelligent life, some civilizations should be millions of years ahead of us. They would have time to send probes, build stations, or transmit signals. Yet after decades of observation, no signal has been accepted as evidence of an extraterrestrial civilization.
