Why No Civilization Can Ever Cross the Galaxy | Brian Greene

#InterstellarTravel,#PhysicsLimits,#FermiParadox,#GalaxyExplained,#cosmicreality Is interstellar travel truly possible—or does the universe itself forbid any species from ever crossing an entire galaxy? In this video, we examine the unforgiving limits set by physics: vast distances, extreme energy demands, time scales that dwarf civilizations, relentless radiation, and the fundamental structure of space-time itself. Drawing on ideas widely discussed by physicists like Brian Cox, we explore why crossing the Milky Way may be not just difficult—but fundamentally impossible. From the constraints of relativity to cosmic radiation and the sheer scale of the galaxy, this breakdown reveals why no biological civilization, regardless of technological advancement, may ever traverse a galaxy in its entirety. This is not science-fiction optimism. It’s physics, numbers, and an uncomfortable reality. Disclaimer: This video is created for educational and storytelling purposes. It is inspired by established scientific theories and public discussions by physicists such as Brian Cox, but it is not a direct quotation, lecture, or official endorsement.
