The object of this paper is to show that the experimental distribution of absorption redshifts of QSOs is consistent with the assumption that these lines are due to the presence of interlopers physically unrelated to QSOs. Some new formulas for the probability that the light emitted by a QSO be interrupted by an object located by chance in its line of sight have been obtained in the framework of the Kinetic Theory of Cosmology (KTC). This allows writing a 'correlation function' between absorption and emission redshifts. The first moments of the contractions of this function are compared with observation. Making use of the hypothesis of KTC, it is possible to estimate the mass of interlopers and other typical features, as well as their contribution to the mean mass density in the universe.
