Fourier analysis of galaxy number counts N(z) calculated for both the large galaxy surveys, SDSS and 2dF GRS, indicates that galaxies have preferred periodic redshifts. There are two ways to interpret this data: 1) that the effect is purely in redshift space and therefore results of some observer bias and/or the universe underwent past oscillations in its expansion rate, or 2) that it is a real space effect and due to the physical location of millions of galaxies on concentric shells with regular spacings. These explanations can be tested and preliminary analysis favours the latter. If this turns out to be true, it means our galaxy is located about 125 million light-years from the centre of the largest super-structure of galaxies ever observed.

Millions of sources in the cosmos have been located by robotic telescopes and various data recorded for them. From that, maps have been created that show how the galaxies are distributed in the sky around our galaxy. Figure 1 shows one such map generated with many tens of thousands of galaxies. At the apex we find our galaxy, but the scale of this map is huge. This is from one such survey, the Sloan Digital Sky Survey (SDSS), and another is the 2 degree Field Galaxy Redshift Survey (2dF#1GRS).

In a recent paper,2 a colleague and I showed from the Fourier analyses on galaxy number counts N(z) calculated for both SDSS and 2dF GRS, that galaxies have preferred periodic redshifts….
