summary - Rössler argues, via what he calls an “Abraham solution” to the Schwarzschild metric (a reinterpretation of general relativity), that LHC-produced micro black holes would behave as classical charged objects rather than evaporate via Hawking radiation, could be gravitationally/electrically trapped inside Earth, and would then grow by accreting matter — reaching planet-destroying mass roughly five years after the LHC’s first full-energy collisions on his calculation. This directly denies the Hawking-evaporation premise the mainstream safety case rests on. CERN commissioned a rebuttal (Nicolai 2008; Giulini & Nicolai 2008, both posted at environmental-impact.web.cern.ch, itself now unreachable and only found archived) concluding the argument “would not pass the referee process in a serious journal” and rests on “an elementary misunderstanding of the theory of general relativity,” with “no logical connection to LHC physics.”
relevance_note - The most publicly visible scientific-sounding dissent, source of much of the 2008 public alarm and a direct trigger for the Wagner-Sancho and ECHR lawsuits; represents the dissenting side in its own words rather than only as filtered through the CERN reply (also summarized here for completeness — a separate node for the CERN/Nicolai-Giulini rebuttal was cut to stay near budget, see orientation note exclusions).
