The forces might not be actual (strong, weak, gravity, electromagnetism). They may act like they are forces in our perspective, but they may be more like aspects or manifestations of gravitons, in both postive and negative space. Null space can be seen as having t = 1, or a universal spin value of 1. This is what can be "tapped" into by use of attached time particle to masses. Fields of particles can also be said to tie together these same particles to constitute a graviton. There might be many, many different permutations of gravitons; and also these gravitons may be cummulative to produce higher order effects. I read something last night in which a well-known physicist (Hoorft?) mentioned that the four known forces sure don't seem to him to behave in actuality like forces. He may be exactly right.
