Mechanism
Mechanism of Large-Scale Structure Formation & Simulations
Dark matter begins clustering early because it does not couple strongly to radiation. Halos merge hierarchically, gas falls into gravitational wells, and baryonic feedback reshapes matter on smaller scales while expansion controls growth globally.
Evidence behind this section3 claims
Large-scale structure forms when small primordial density fluctuations grow through gravity in an expanding universe.
