Since I am still working on this...
Gravity in my model is "stationed" within negative space. Negative space has one central origin which acts as one point for all the negative space origins. Time is directed out from this central point to create an infinite realm of null space...it could act either to push all the positive space origins out to infinity, or it acted to pull all the positive space origins onto the barrier between negative space and positive space. This barrier is where the actions of the strong force acts. Another inner barrier between the strong force barrier and the central origin of negative space is the weak force barrier. The negative space central origin may be from where gravity acts...I repeat, may be...but that origin appears to be the central point from which it does act, but I am not sure that the gravity is carried out in a straight line past the weak force origin and the strong force origin. Somehow all these forces act through null space, negotiated by time (the origin of time is in null space, and I call it a non-apparent origin, but it becomes an apparent origin at infinity). Maybe I am contrained by 2d thinking.
