What makes Von Neumann probes impossible to exist? Is it likely that Von Neumann came up with the concept only to attract attention and funding, while not believing they are possible? -
UET Science Society - You'd launch a Von Neumann probe (that is, a spacecraft that can replicate itself) equipped with an interstellar propulsion system and send it to a neighboring star system.
