Scientific paper

Models in which galaxies and clusters have a nongravitational, possibly explosive, origin seem to be better candidates for the progenitors of large sheets and bubbles. However, such a scenario would not lead one to expect the perfectly regular lattice of such structures which is observed. It is shown here that a random cellular model, which mimics the galaxy distribution formed as matter is swept up into shells around expanding void regions or by cosmic blast waves, reproduces the observed Great Walls, voids, and periodic structures without undue difficulty.
