Cosmic structure formation refers to the complex and intricate process by which the large-scale arrangement of matter in the universe has evolved over cosmic time. It encompasses the development of structures such as galaxies, galaxy clusters, superclusters, and the cosmic web, which constitute the cosmic fabric. Understanding cosmic structure formation is central to cosmology and astrophysics because it sheds light on the origins and evolution of the universe.

This intricate process is governed by the interplay of various cosmic forces, including gravity, dark matter, and dark energy. Gravity acts as the cosmic sculptor, attracting matter into denser regions and forming gravitational wells, where galaxies and clusters of galaxies eventually congregate. Dark matter, a mysterious and invisible component of the universe, plays a pivotal role in this process, providing the gravitational framework upon which ordinary matter assembles.
