Cosmic Queries - ALIENS! with Jake Roper
Neil deGrasse Tyson and co-host Chuck interview YouTube science communicator Jake Roper in a Cosmic Queries episode focused on aliens in movies and TV. They discuss the plausibility of alien diseases, energy weapons, and iconic movie aliens, as well as how humanity might react to first contact, whether governments would hide evidence of intelligent life, and why self-replicating machines are a likely form of extraterrestrial visitors. Throughout, they compare cinematic depictions with basic physics, biology, and astrobiology concepts to assess what could and could not work in reality.
