Crafting Spacecraft from Interstellar Visitors

Avi Loeb argues that civilizations could transform interstellar objects like Oumuamua, Borisov, and ATLAS into spacecraft by converting their raw materials into self-contained probes. These hitchhiking crafts could depart their hosts and, with optimal trajectories, even seed life on other worlds, potentially visiting habitable zones around Sun-like stars within a billion years. The idea ties into the Galileo Project and UAP research, and Loeb suggests that humanity could become an interstellar species by leveraging naturally roaming material from other star systems.
