summary - Official pre-startup safety review commissioned to assess speculative catastrophe scenarios (vacuum decay, magnetic-monopole catalysis, and especially strangelet production) at Brookhaven’s Relativistic Heavy Ion Collider. Argues black-hole production parameters at RHIC energies are “absurdly small” (this predates the large-extra-dimension TeV-gravity scenarios central to the later LHC debate) and gives its most detailed treatment to strangelets, identifying four conditions that would all have to hold simultaneously for a dangerous strangelet (large strangelets stable; intermediate-mass strangelets metastable; negative charge along the stability line; production in the collider) and arguing each independently is implausible. Leans heavily on the cosmic-ray survival argument, citing the Moon’s billions of years of undisturbed cosmic-ray exposure as evidence against dangerous strangelet formation.
relevance_note - The RHIC-era analogue of the LSAG/Giddings-Mangano safety case - an officially commissioned primary safety analysis (not just a literature review) whose strangelet-stability-conditions framework the later LHC-era discussion inherits; explicitly rests on the shared cosmic-ray/Moon-survival premise rather than adding new data to it.
