Void-star fission is a scientific model describing how a heavy void-star isotope can capture a rift neutron, form an excited core, and divide into smaller fragment stars.
Process
The model begins when a rift neutron reaches a heavy V-236 nucleus. Capturing the neutron creates V-237*, an excited compound core that cannot remain stable.
The core separates into two fragment stars and releases additional neutrons, gamma-v energy, and heat.
Chain reaction
Released neutrons may strike nearby heavy cores. If enough suitable cores are present, each split can cause further splits and create a branching chain reaction.
Status of the model
Void-star fission is an in-universe model and should not be confused with a description of real stellar physics. It is used in Nullhaven classrooms to explain local star behavior.
