summary - Plaga argues that TeV-scale black holes, if produced at the LHC, could (under a quantum-mechanical microcanonical treatment building on Casadio & Harms 2002) reach a long-lived quasistable state rather than evaporating promptly via Hawking radiation, then accrete ambient matter at the Eddington limit and become dangerous on a timescale of years to decades. He argues this specific scenario is not excluded by Giddings & Mangano’s (2008) astrophysical/cosmic-ray survival bounds, because objects in this regime would not have been produced, or would not behave the same way, in natural high-energy collisions — i.e. he claims the official exclusion has an unargued gap rather than a proven closure. Proposes operational safeguards (staged energy ramp-up, full event monitoring) rather than halting the LHC.
