A few questions I would pose, in that it's my understanding that there is more matter than anti-matter in the universe. If this is indeed true (I don't know, is it?) then why would the repulsive force of the anti-gravitron overcome the attractive force of gravity? (A)
Also, gravity (thus presumibly "anti-gravity") is a weak force. Would this anti-gravitron be a strong enough force to over come other, more prevelant influences on a universal scale? (B)
Lastly, if this particle exists and is the driving force behind universal expansion, wouldn't it have to exist uniformly in order for the universe to expand, well, uniformly? (C)
I don't know maybe I misunderstand your theory, and with my limited knowlege of such things I dont' even know if my questions make sense. But thats what comes to mind for me.

These are all good questions. As for (A&B), I have come up with three possible answers to these questions.
a. There is more anti gravity causing the universe to ultimately expand to infinite rather than contract. but this explanation leads to other questions like: "why do other systems of gravity (like galaxies, solar system(s), and black holes) manage to coexist along this dominant anti-gravity"? this brings me to explanation b
b. There is equal amounts of gravity and anti-gravity, but due to their very nature, they can coexist without destroying the effects of the other. for example, perhaps if matter is close enough to other matter, normal gravitational force, as we know it, behaves normally (and because of this, systems such as black holes, galaxies, and planetary systems hold themselves together). But since gravity is such a weak force, that it takes an insignificant amount of distance for anti-gravity to take its effect on the large scale (the spaces in between the galaxies) to not only exert its influence, but to get stronger due to the increasing distance. This in turn causes a chain of events, like that in a black hole, but the opposite. just like the self-sustaining, and self-strengthening contracting effect gravity has on a black hole, the spaces in between the spreading galaxies have a self-sustaining, self-strengthening system of expansion, and repulsion.
c. Perhaps there is an equal amound of gravity, and antigravity. but the additional outwards push, provided by the big bang disrupted this equilibrium, thus, causing the universe to expand to infinite.
C: I have 3 possible thoughts on this. Either:
a. It exists in some kind of relation to matter/dark matter, to the same effect that gravity has on matter, and therefore exists within the matter. or to my second proposition b
b. Rather than thriving near any type of matter, dark matter etc... it thrives in voids of matter and/or energy, another property that puts it opposite to normal gravity.
c. It exists semi-uniformly (I say "semi" because perhaps its effects are stretched and amplified near certain properties, like mass) in the quantum foam that makes up the universe and therefore, has a broader influence.
These are actually really good questions, and upon thinking about them, gives me another hypotheses that I am going to post.
