Thank you all for corrections and clarifications.
I had confused Antimatter in particle theory (where there is no gravity) and Dark matter, which has no explanation in particle theory and maybe probably shouldn't be necessary for a unified model that describes n-body gravity at astrophysical and particle scales.
