Cosmic Expansion vs. Galactic Density

Observing galactic density as a function of increasing distance (and, correspondingly, earlier times given the travel time of light) should provide evidence as to whether a \'steady-state\' (non-expanding) or Big-Bang-driven expanding universe is the more defensible cosmology. Working independently, but later discovering additional recent work in this area by Heymann, I attempt to address this question by simulating galactic densities for the two types of cosmological model. Results suggest that the non-expanding universe may be more consistent, or at least less inconsistent, with both observation and expectation. Further, they are consistent with conclusions drawn by Heymann from his recent studies.
