The Standard Model of elementary particles (SM) is a quantum field theory of color and electroweak interactions . It exists inherently in flat spacetime and lacks therefore gravity. It has no candidate for dark matter. The electric and color charges get explicitly broken through the quantum loops by the Poincare breaking scale. It will be shown in this talk that GR can emerge in a way securing the conservation of charge and color provided that there exists a beyond-SM sector (BSM) made up primarily of new massive fields. The BSM easily accounts for the current dark matter data as it does not have to couple to the SM. The dark matter must weigh below 400 GeV for possible SM-BSM couplings not to destabilize the Higgs mass.
