Why We May Be The Only Civilization In The Galaxy | Feynman Explains

#RichardFeynman #Galaxy #physics Look up at the night sky. Our galaxy alone contains around 400 billion stars and potentially trillions of planets. Many of those worlds are older than Earth. Many may have oceans, atmospheres, and the right conditions for life. So here is the unsettling question: if intelligent life should be common in the universe… why haven't we seen anyone? In this video, we explore the Fermi Paradox through Richard Feynman's physics-first perspective — examining the possibility that Earth may be extraordinarily rare, the idea of self-replicating probes that could colonize a galaxy, the chilling logic of the Dark Forest hypothesis, and the terrifying concept known as the Great Filter. If civilizations should have had billions of years to expand across the Milky Way… the silence of the universe becomes one of the deepest mysteries in science. 📚 SOURCES Enrico Fermi — Conversation on extraterrestrial civilizations, Los Alamos discussions (1950) Frank Drake — Project Ozma and the Drake Equation, 1961 Nick Bostrom — Existential Risks: Analyzing Human Extinction Scenarios, Journal of Evolution and Technology, 2002 Michael H.
