Abstract
Presented is a clear description of the mechanism by which galaxies acquire significant rotation. Beneath the apparent random motions and concentrations of galaxies lies the simplicity and regularity of a cosmic-scale cellular structure. It is explained how the dynamics that sustain this cellular structure is responsible for (1) the initial linear motion of galaxies, particularly of ‘field’ ellipticals; (2) the oscillation of the trajectories of galaxies; and (3) the preponderance of gravitational mating of galaxies at favorable locations of the cosmic cellular structure. The importance of the boundaries between cosmic cells is recognized, for this is where the bombardment of galaxies from adjacent cells takes place, leading to random collisions. These collisions, in conjunction with induced trajectory oscillations, result in orbital interactions with varying degrees of angular momentum —from stellar-scale to galactic-scale. As a bonus, the explanation of the so-called <i>random motions</i> of galaxies becomes self-evident and the galaxy <i>morphology-density mystery</i> is resolved. A clear answer is given to the decades old question of why ellipticals dominate the population of the densest regions of a cluster, while spirals are observed to comprise a majority in the elongated (filamentous) region of a cluster.

The eminent objectivist philosopher Ayn Rand was noted for the clarity of her ideas
Dynamic Steady State Universe (DSSU) cosmology holds that the universal space medium is the ultimate bedrock of Nature, and further, that the space medium expands and contracts regionally and resulting in a cosmic-scale cellularly-structured universe
If galaxies were distributed within a cluster like the unperturbed way in which stars are distributed within globular clusters, there would be no way to initiate significant galactic interaction —there would be no way to bring about large-scale galaxy rotation
Summary
The eminent objectivist philosopher Ayn Rand was noted for the clarity of her ideas. She learned and taught: “Definitions are the guardians of rationality, the first line of defense against chaos of mental disintegration.”. The term space medium, or universal space medium, refers to the nonmaterial aether (as define by DSSU theory*) that permeates ALL space. DSSU cosmology holds that the universal space medium is the ultimate bedrock of Nature, and further, that the space medium expands and contracts regionally and resulting in a cosmic-scale cellularly-structured universe. It is a model based on the premise that all things are processes. Gravity domain: is a cosmic region within which all comoving bodies fall inward; and from which no gross body can escape It is permeated by an aether (defined above) that determines the domain’s dynamic and kinematic characteristics.
