It is thus possible that there are astrophysical objects where it is violated. Such objects were termed superspinars [272], but it is part of a larger class of objects which would arise if singularities (in the classical theory of GR) would be visible. The full spacetime description of superspinars and other such similar objects is lacking: to avoid singularities and closed-timelike curves unknown quantum effects need to be invoked to create an effective surface somewhere in the spacetime."}],"limit":50,"offset":0}
