Cold Dark Matter Simulation (CDM Simulation)

Cold Dark Matter (CDM) simulation is a computer-based method used by scientists to model how the universe's large-scale structures, like galaxies and galaxy clusters, form and evolve. It assumes dark matter consists of slow-moving particles that interact mainly through gravity. By simulating these particles from the universe's early moments, researchers can observe how tiny density fluctuations grow over time, leading to the cosmic web of galaxies we see today. CDM simulations help scientists understand the distribution of matter in the cosmos and test theories about the universe's history and composition.
