Superconductivity in low carrier density metals challenges the conventionalelectron-phonon theory due to the absence of retardation required to overcomeCoulomb repulsion. In quantum critical polar metals, the Coulomb repulsion isheavily screened, while the critical transverse optic phonons decouple from theelectron charge. In the resulting vacuum, the residual interactions betweenquasiparticles are carried by energy fluctuations of the polar medium,resembling the gravitational interactions of a dark matter universe. Here wedemonstrate that pairing inevitably emerges from "gravitational'' interactionswith the energy fluctuations, leading to a dome-like dependence of thesuperconducting $T_c$ on carrier density. Our estimates show that thismechanism may explain the critical temperatures observed in doped SrTiO$_3$. Weprovide predictions for the enhancement of superconductivity near polar quantumcriticality in two and three dimensional materials that can be used to test ourtheory.
