Non-observation of strangelets
The argument
If strange quark matter were the ground state, stable lumps of it (strangelets) could plausibly be produced in collisions or survive as relics from astrophysical events. Because no strangelet has been observed in heavy-ion collision experiments and cosmic-ray and terrestrial searches have found no confirmed strangelets, decades of null results weigh against the hypothesis, though the inference is limited if finite-size effects destabilize small strangelets even when bulk strange quark matter is stable.

Granting the null results from heavy-ion experiments and cosmic-ray and terrestrial searches, they weigh against the hypothesis only a little. Expected production rates and relic fluxes are highly uncertain. And if finite-size effects destabilize small strangelets, bulk stability would be compatible with no strangelets ever being seen in these searches. The force of the argument lies in how consistently the many independent searches agree, not in any single one.

The inference goes through only weakly: the null results in heavy-ion strangelet searches and cosmic-ray and terrestrial searches count against the hypothesis, but their force depends on how likely stable strangelets were to be produced or to survive in the first place. Because finite-size effects may destabilize small strangelets even when bulk strange quark matter is stable, and expected production rates in colliders are low, the non-observations constrain small lumps of strange matter far more directly than they test the bulk ground-state claim. The argument lowers the claim's plausibility without approaching a refutation.
