| The redshift distribution of galaxies (SDSS data) on the logarithmic map of the universe is explained by the linear expansion hyperspherical model. Our computed result show that the density distribution of galaxies take two peaks at redshift 0.108 and 0.362 and two minimum at redshift 0.229 and 0.510. It is shown that our model may fit the map well. It is proposed that celestial sphere should be defined by the comoving coordinates system. |
