Abstract We address primarily the question of why it is that early light has taken so long to reach us given that initially all galaxies were so close together in a big bang model. We perform a pair of simple numerical integrations in order to trace the present photon trajectory backward in time. We find that this data not only answers our initial question but is also sufficient to make several model predictions and alternative “world maps” of galactic trajectories.
