Cosmic web simulation is a computational technique used in astrophysics and cosmology to model and study the large-scale structure of the universe known as the cosmic web. These simulations provide a virtual representation of how galaxies, galaxy clusters, dark matter, and other cosmic structures are distributed throughout the universe, taking into account the effects of gravitational interactions and cosmic expansion. Simulations often focus on modeling the distribution of dark matter, as it makes up the majority of the matter in the universe. Dark matter’s gravitational influence plays a central role in shaping the cosmic web.

Cosmic web simulations are used to test cosmological models, investigate the nature of dark matter, study the distribution of galaxies, and gain insights into the large-scale structure of the universe.
