Self-replicating probes could outnumber the galaxy's stars
Original: Eine einzige Raumsonde, die an einem fremden Stern aus Asteroiden zwei Kopien ihrer selbst baut, hätte nach 10.000 Jahre
A thought experiment about von Neumann probes is circulating online: a single space probe reaching a foreign star and building two copies of itself from asteroid material would, after 10,000 years, have produced more descendants than the Milky Way has stars. The post links the idea to NASA and explores why self-replicating machines are considered both a powerful exploration concept and a potential risk.
Why now: The exponential-growth math behind self-replicating space probes is striking and fuels debate about extraterrestrial exploration and its risks.
