Assuming the validity of the general relativistic description of gravitation on astrophysical and cosmological length scales, we analytically infer that the Friedmann-Robertson-Walker cosmology with Einsteinian cosmological constant, and a vanishing spatial curvature constant, unambiguously requires significant amount of dark matter. This requirement is consistent with other indications for dark matter. The same spacetime symmetries that underlie the freely falling frames of Einsteinian gravity also provide symmetries, which for the spin one half representation space, furnish a novel construct that carries extremely limited interactions with respect to the terrestrial detectors made of the standard model material. Both the `luminous' and `dark' matter turn out to be residents of the same representation space but they derive their respective `luminosity' and `darkness' from either belonging to the sector with (CPT)^2 = + 1, or to the sector with (CPT)^2 = - 1.
