The Dark Forest: Why an Extraterrestrial Civilization Would Stay Silent Instead of Greeting Us

In 1950, physicist Enrico Fermi asked, "Where is everybody?" The question became the Fermi paradox. The Milky Way contains at least hundreds of billions of stars, NASA has confirmed thousands of planets beyond the Solar System, and yet humanity has no evidence of life beyond Earth or a confirmed technological signal sent by another civilization.

Dark Forest theory offers an answer: civilizations may exist, but they choose not to reveal themselves. A broadcast can disclose a society's location, technology, and resources before either side understands the other's intentions. In this reading, an Earth signal is not a greeting. It is a young society announcing its position before it knows who is listening.
