Manifestation is order. String theory suggests everything comes from chaos, and becomes the order we see. A big bang would be chaotic, but the manifestation that follows is not. The Egyptians were focused on the need for order, and it was the pharoah's duty to maintain order. Greeks adopted ideas from those around them and switched from believing gods created and controlled everything as they pleased, to believing reason, is the controlling force of the universe. Together we get the following science of universal order.

Origin and Chemical Evolution of the Elements
To understand the chemical evolution of the universe, we need to determine the elemental composition of the gaseous matter and its relation to cosmic epoch and physical environment. Abundances of various species are expected to vary with gas density, star-formation rate, and proximity to galaxy structures. In the very early evolution, H, He, and trace amounts of other light elements such as D and Li were created in the expanding Big Bang fireball. At later times, stars converted the gaseous products of the Big Bang into heavier elements and returned the processed elements back to the interstellar medium via stellar winds and supernova explosions. Subsequently, the metal-enriched interstellar gas was transported to the IGM by galactic outflows, gravitational interactions, and mergers of galaxies. Numerical models of IGM enrichment (Gnedin & Ostriker 1997) predict a strong dependence of metallicity on density; the highest density regions are expected to reach 0.1 solar metallicity at , while the matter in the voids remains nearly pristine. Subsequent stellar processing created new elements and slowly modified the nucleosynthetic imprint of the Big Bang. These processes of stellar element production and destruction have continued to the current epoch. A study of elemental abundances as a function of lookback time and environment provides a detailed, quantitative assessment of the history of element production and destruction.
