The danger hypothesis whose probability the whole strangelet analysis prices. The paper’s own candidate terminators of the growth, none of which QCD knowledge can confirm or exclude: (a) a stable positively-charged species may be reached during growth, which electron shielding then freezes; (b) the lightest metastable strangelet may be isolated by many baryon-number units from the next stable one (as the A=8 gap stops alpha-alpha fusion in stars), so growth by single-nucleon absorption cannot proceed; (c) capture-energy release may fragment the strangelet into small unstable pieces. Growth would continue at least until released energy vaporizes surrounding material away. Note the scenario requires production velocity below ~0.1c (faster strangelets break up before stopping), hence lifetime > ~1e-7 s to traverse detector and shielding.
