Astrophysicist Avi Loeb urges interstellar expansion for human survival

Humanity faces extinction from a single pandemic, according to astrophysicist Avi Loeb, who urges interstellar expansion for survival. Loeb argues that being a single-planet civilization makes us vulnerable. He proposes establishing an interstellar civilization, potentially through artificial space platforms, as an insurance policy against catastrophic events. He suggests that discovering extraterrestrial technology could inspire humanity to prioritize space exploration and develop advanced technologies like synthetic biology for long space journeys.
