statement
If bulk strange quark matter is stable over the full range of baryon numbers, then macroscopic strange-matter nuggets should exist in the Galaxy and arrive as a component of cosmic radiation colliding with Earth ('nuclearites'), producing characteristic, experimentally detectable encounter signatures — so the existence of stable strange matter is empirically testable from Earth, and Earth's own long history of such encounters without incident is itself an exposure record: stable strange matter raining on Earth does not convert or destroy it.

Reasoning:

  1. The abstract’s chain: given Witten-stability at nearly all A, nuggets of intermediate baryon number are expected to exist astrophysically; the paper’s premise is that such nuggets are ‘in collision with Earth’ as a novel form of cosmic radiation, and it ‘suggest[s] experiments to detect these encounters’.
  2. This supplies, for strange matter, the analogue of the cosmic-ray argument for black holes: the hazardous object’s existence implies a natural flux through Earth, so terrestrial persistence plus dedicated null searches constrain stable strange matter empirically rather than only theoretically — the role this source plays in the safety-case graph.
  3. Depth limitation (flagged): the full Nature text (312, 734-737, 1984) is paywalled and no legal open copy was found (CERN Document Server record is bot-walled; no arXiv version; KEK/INSPIRE hold no fulltext). The paper’s quantitative content — nuclearite flux estimates as galactic-halo dark matter, velocities (~250 km/s galactic virial), energy-deposition/light-emission signatures, meteor-like traversal detectability — could not be verified and is deliberately not asserted here; only the abstract-level argument is extracted.

Step 6 verdict

Verdict: approved (checked). Reconstruction: (P1) bulk stability at nearly all A implies astrophysically produced nuggets exist; (P2) some galactic flux reaches Earth; (C) H-32 is empirically testable, and Earth’s persistence under that flux shows arriving stable strange matter does not convert Earth. Conditional on P1-P2 the conclusion follows (exposure logic). Hidden premise surfaced: a production mechanism actually populating intermediate baryon numbers with non-negligible flux - a genuine premise priced in steps 7-8, not completion-by-force, since the source asserts it. Scope honesty noted: the node deliberately asserts only the abstract-level chain (full text inaccessible), and the conclusion is correctly limited to what arrives (nuclearites) rather than stretched to collider strangelets. Valid at the asserted strength.
