WebIn theoretical physics, fine-tuning is the process in which parameters of a model must be adjusted very precisely in order to fit with certain observations. This had led to the discovery that the fundamental constants and quantities fall into such an extraordinarily precise range that if it did not, the origin and evolution of conscious agents in the universe would not be … WebAnd, therefore, there are no fine-tunings or hierarchy problem in a theory describing all observed phenomena in particle physics. The only experimental evidence for the presence of another scale in Nature is gravity, meaning that any realistic description of it must have at least two widely separated essential scales, that of Fermi ( M F ∼ 100 GeV) and Planck ( …
