Perhaps, real particles {ylem} can come from virtual-particle pairs, making universe more homogeneous.
Perhaps, new subatomic-particle types {ghost condensate} can make outward pressure that prevents gravitational collapse.
Perhaps, cold-dark-matter particles are superpartner particles {lightest superpartner particle} (LSP).
Perhaps, dark matter is neutrinos or supersymmetric particles {photino} {Zino} {Higgsino}.
Perhaps, cold dark matter is subatomic particles {weakly interacting massive particles} (WIMP) {neutralino} from universe origin that do not interact with electromagnetic radiation and move slowly.
