We've presumed the constancy of atomic nuclear processes, but ...
[under construction]
The possibility of nuclear-fail exists cosmically: the physicist
assumes the constancy of every detail (he) discovers, yet as the
ancients discovered the eclipse of the sun by the moon, so we must
watch for the failure of the most subtle neutrino ... a fact the
physicist calls the neutrino-paucity, referring to the solar
neutrino flux ... but we watch the effect upon the cosmos as it
affects living on Earth ....
scenarios
cosmic center neutrino sudden-paucity
failure of spontaneous fission 235U triggered devices
reliance on accelerator-generation of neutrons for trigger
cosmic center neutrino sudden-excess
rapid deterioration (radiodecay) of nuclear devices
rapid destruction (meltdown) of nuclear devices
neutrino 'LASER' deterioration/destruction of nuclear devices
cosmic-gravitational rhythmic-reflection of ancient neutrino event
near-by supernova-event deterioration/destruction of nuclear devices
consequential armageddon
conventional war at discovery of nuclear failure
follow-up nuclear war at restoration of nuclear devices
sudden restoration of nuclear spontaneity (cosmic paucity scenario)
