A computer simulation of the gravitational field of the universe has been developed that precisely predicts the observed overall redshift due to Doppler and Gravitational components. It applies to both nearby and distant galaxies, and is more accurate than Hubble's Law. It is called the COI universe model. Many other unusual cosmic observations: the KBC void size and density; the Fingers of God effect; the Galactic windup dilemma; and the age of distant galaxies are also explained. No other simulation has ever predicted these things. It uses only experimentally proven physics — no dark stuff. It hangs on one supportable assumption about the start of time. This is for physicists and astronomers yet kept simple enough for a layman. There is even a section to challenge Bible fanatics because the center of the universe is revealed.
