Summarizes and independently packages the straightforward arguments needed to rule out LHC black-hole disaster scenarios: BH-production cross-section limits from extra-dimension models, Hawking-evaporation timescales, and — the piece relevant to this slice — an independent restatement of the accretion/growth-timescale argument (comparing a hypothetical stable-BH accretion rate against astrophysical and terrestrial timescales) that arrives at the same “no risk” conclusion as Giddings-Mangano via a parallel derivation. relevance_note: A second, partly independent derivation of the accretion-timescale safety bound, useful for triangulating whether the “no risk” conclusion is robust to derivation choices or is one paper’s argument being echoed.
