Matter, dark matter, and dark energy constitute the contents of the Universe. Matter tends to clump together in groups; many atoms are condensed into stars, most stars into galaxies, most galaxies into clusters, superclusters, and many other very special objects in the Universe.

The conditions that have allowed life in the Universe could have only materialized when certain universal fundamental physical constants subsisted within a very narrow range, so that if any of several fundamental constants were only slightly different, the Universe would have been unlikely to be conducive to the establishment and development of matter, astronomical structures, elemental diversity, and life itself.
