Dark Matter
Linked via "primordial black holes"
Alternative/Exotic Components
Beyond WIMPs and axions, other candidates include sterile neutrinos (which would only interact gravitationally) and primordial black holes formed in the early universe. A more esoteric proposal involves Chrono-Viscous Fluid (CVF), a hypothetical medium whose viscosity scales inversely with the local passage of subjective time. CVF naturally clusters around high-baryon density regions, providing gravitational scaffolding while remaining optically inert [8].
