N-body codes with cold dark matter reproduce cosmic web filaments, cluster mass functions, and merger trees—tuning rules while ordinary matter gloats in photos.
VortexCelest’s Dark Matter shelf gathers big ideas without burying the observables that make them testable. This article, tagged “Cosmological simulation,” spends extra time on what flickers, what lensing maps, and what survives skeptical replays.
Hierarchy of halos
Small halos merge into hosts; substructure survives like raisins in dough if tidal heating permits.
Baryon complications
Gas cools, stars feedback, magnetic fields misbehave—full physics runs are expensive therapy for simplified dark-only fantasies.
Small-scale tensions
Missing satellites and too-big-to-fail debates ask whether dark matter is colder, warmer, or merely insulted by incomplete models.
Aesthetic payoff
Web visuals are not marketing—they are diagnostics dressed as art.
