We performed the check of supposition about the possibility of manifestationof the previously observed phenomenon of central symmetry of the celestialsphere through existence of the opposite quasars. We discovered the existenceof some pairs of quasars located opposite each other with close by formprofiles magnitudes of luminosity in the ranges u, g, r, i, z, when correlationcoefficient close to 1. We discovered that the percentage of the pairs withcorrelation coefficients Rxy>0.98 for the opposite located quasars issignificantly higher than that for the random pairs.  The analysis of the dependence of this exceedance from the artificialbreaking of the central symmetry has shown, that it practically disappears withsymmetry breaking by more than 0.05 degrees. Thus we can confirmed themanifestation of the central symmetry of celestial sphere through existence ofthe central symmetrical pairs of quasars, which can be interpreted as the pairsof images of the same object.  We shown the possibility of a theoretical modeling of the observeddependencies in the closed Universe model. It can be supposed, that arelatively small amount of the discovered pairs of the opposite quasars isconditioned by the fact, that the opposite objects for most of the quasars aregalaxies, which are not included to the chosen as initial source of data quasarcatalog SDSS-DR5.
