cosmic structure

Cosmic structure refers to the large-scale arrangement of matter in the universe. It includes vast networks of galaxies grouped into clusters, superclusters, and interconnected by filaments of dark matter, forming a cosmic web. These structures emerged from tiny density fluctuations in the early universe, amplified over billions of years by gravity. Between these dense regions lie enormous voids with few or no galaxies. Understanding cosmic structure helps scientists explore the universe's evolution, the role of dark matter and dark energy, and the fundamental processes shaping the cosmos on the grandest scales.
