It just does not have unlike charges. Like charges attract like charges for gravity. So this is a bit like the C charge. But it comes very late in the break down of the unified field into gravity and GUT, and GUT into Strong and electro-weak forces, and electro-weak into em and weak force.
It is not manifested in the 3-D universe until just before the break up of the electro-weak force by the Higgs particle.
I am having difficulty imaging a multi-dimensional mechanism based on compactified dimensions that could explain the force of gravity, or more precisely the existence of mass.
But let me try:
Gravity exists from the very first symmetry breaking as the unified field split into the GUT field and gravity. But mass did not come into existence until much later.
I would associate that symmetry break with the compactification of the 16 D from 26 to 10D, that allowed the creation of fermions, both matter and anti-matter. Inflation happens next without mass to slow it down. Inflation occurs in 3-D space. So by then we have both the early 16 D compactification and the later 6 D compactification that I think is associated with inflation.
Axions and the C charge came from the 6 D thread attachments of particle pairs, in this model, as matter and anti-matter ultimately annihilated each other, almost, and the axions precipated into space from the thread breakup, as almost massless particles, which retained the C charge of the original 16 D compactification.
So in this model, gravity must also be associated with the 16 D compactification. Afterall the graviton is a boson that can exist on a closed string. This leads me to postulate that the creation of photons and gravitons comes from the breakup of the 16 CD (Compactified Dimensions) threads connecting all fermions into various closed strings. Both photons and gravitons are closed strings.
OK I'm stuck. My stream of consciousness has been dammed. No one has probably read this far any way.
