What we see as mass is negative space in my terminology fixed with time elements (what we see as spin). For an example, choosing a charged particle, we have the charge/acceleration axis pointing directly outwards; the momentum axes are curved from a point perpendicular to this charge axis. In negative space you have the converse: the gravity/mass indicative axis points inward and is the acceleration axis, and the charge characteristics are the curved momentum axes. Graviton characteristic is a converse switch between positive and negative space. There could be some type of oscillation occurring that has this converse switch.
This is a simple example, but I think there are more complicated permutations occurring also, such as in relation to multiple particles such as electrons.
