Nicolai reviewed Otto R*ssler's research paper on the safety of the LHC and issued a statement highlighting logical inconsistencies and physical misunderstandings in R*ssler's arguments. Nicolai concluded that ``this text would not pass the referee process in a serious journal.'' Domenico Giulini also commented with Hermann Nicolai on Otto R*ssler's thesis, concluding that ` _his_ argument concerns only the General Theory of Relativity (GRT), and makes no logical connection to LHC physics; the argument is not valid; the argument is not self-consistent.'' <sep>, Pronoun: his <sep>, A: Hermann Nicolai <sep>, B: Otto R*ssler
