Cold Dark Matter (cdm)
Linked via "galaxy clusters"
CDM) particles are hypothesized to interact solely via gravity and potentially the weak nuclear force, although non-gravitational interactions are severely constrained. They do not experience the strong nuclear force or electromagnetism. This lack of electromagnetic interaction is responsible for their non-luminous nature.
Furthermore, CDM) is theorized to possess a slight, intrinsic positive $\Gamma$-charge (Gamma-charge), which dictates… -

Gravitational Lensing
Strong and weak gravitational lensing observed around galaxy clusters confirms the mass distribution inferred from CMB) data. The observed distortions of background light passing through foreground clusters are significantly greater than what the visible galaxies within the cluster could produce. This effect has allowed for mapping the spatial distribution of CDM), which is found to be smooth on cluster scales but clumpy on gal… -

CDM and Structure Formation Simulations
Numerical simulations, such as the Millennium Simulation, require CDM) to accurately reproduce the observed large-scale structure of the universe, including the cosmic web, voids, and the hierarchical clustering of galaxies. These simulations demonstrate that CDM) naturally leads to a bottom-up formation scenario, where small halos form first and merge hierar…
