Why haven't humans encountered aliens yet? Are aliens hiding their existence so thoroughly?

리뷰엉이: Owl's Review

Published on Nov 11, 2023

About :

The universe is so huge that extraterrestrial intelligence is bound to exist. But Enrico Fermi asks why we have never met aliens before. This is Fermi's paradox. In 1983, astronomer and author David Brin argued that the universe is like a very dark forest. Aliens have no idea whether other civilizations in the universe are friends or enemies, so they hide their existence thoroughly. This is the dark forest hypothesis. It is a theory that there are many extraterrestrial civilizations all over the universe, but since they do not know whether other extraterrestrial civilizations are friendly or hostile, they are afraid of being destroyed by other civilizations, so they quietly maintain a state of hostility.
