<b>Theoretical Formation and Geopolitical Risks of Fissile Material Asteroids</b>

This paper explores the hypothesis that remnants of supernova explosions could form asteroids rich in fissile materials such as uranium-235. Through rapid neutron capture (r-process) nucleosynthesis, heavy elements are synthesized and distributed throughout stellar remnants. If such fissile-rich asteroids survive planetary formation and persist in regions such as the Kuiper Belt or Oort Cloud, their eventual gravitational capture by Earth could result in gamma-ray bursts, neutron emissions, or localized radiation. These phenomena could mimic the signature of a nuclear explosion, posing a serious risk of misinterpretation by global nuclear monitoring systems and potentially triggering international conflict. The paper evaluates entry dynamics, momentary criticality, detection protocols, and offers recommendations to integrate natural criticality scenarios into existing nuclear response frameworks.
