6:16Now PlayingIn this discussion, Neil deGrasse Tyson, Paul Mecurio, and Charles Liu respond to audience questions about alien civilizations, global unity, human conflict, the Fermi Paradox, and whether humanity could truly come together in the face of an extraterrestrial threat. The conversation explores both optimistic and pessimistic views of human nature, referencing history, science fiction like Arrival and Star Trek, and the possibility that contact with advanced aliens could fundamentally change civilization.
