LARGE SCALE PERIODICITY IN REDSHIFT DISTRIBUTION

We review the previous studies of galaxies and quasar redshifts discretisation. We present also the investigations ofthe large scale periodicity, detected by pencil–beam observations, which revealed 128 (1/h) Mpc period, afterwardsconfirmed with supercluster studies. We present the theoretical possibility of obtaining such a periodicity using atoy-model. We solved the Kepler problem, i.e. the equation of motion of a particle with null energy moving inthe uniform, expanding Universe, decribed by FLRW metrics. It is possible to obtain theoretically the separationbetween large scale structures similar to the observed one.
