The WIMP dark matter picture is only consistent its mass \$M M\_Pl\$ in order to maintain classicality. The dynamics of a super-fluid are given by the excitation spectrum of bound state quasi-particles, rather than the center of mass motion of constituent particles. If this relic is a fermion with a repulsive interaction mediated by a heavy boson, such as neutrinos interacting via the \$Z^0\$, the condensate has the same quantum numbers as the vierbein of General Relativity. Because there exists an enhanced global symmetry \$SO(3,1)\_spaceSO(3,1)\_spin\$ among the fermion's self-interactions broken only by its kinetic term, the long wavelength fluctuation around this condensate is a Goldstone graviton. A gravitational theory exists in the low energy limit of the Standard Model's Electroweak sector below the weak scale, with a strength that is parametrically similar to \$G\_N\$.
