New Explanation of Hubble's Red Shift

The balance system between dark massenergy (with a spacetime center) and stellar massenergy (with a massenergy center) cause a flat universe. In the flat universe, the Hubble$’$s redshift is caused by the Lorentz transformation (Einstein transformation). This paper will discuss about the relationship among Einstein transformation, Doppler effect, and Hubble$’s$ redshift under the balanced and flat universe model. http://meetings.aps.org/link/BAPS.2014.APR.Y9.1
