OK, so *how* does it affect the matter? You should be able to express
that mathematically. In fact, to develop a model, you *must* express it
mathematically.

Example: The sun's mass affects a planet by its gravity.  OK, so *how* is
the planet affected?  In Newtonian gravity the effect is an attractive
force, you define a few things G, M, m and r and the force is equal to
GMm/r^2.

(I'm overlooking completely the reasoning behind why you consider your
"good ideas" to be good in the first place for this post)


OK, using the convention that an attractive gravitational force is 
positive, therefore repulsive is negative, your bizarre idea has this
property that from far away it is attractive (positive), at a certain 
radius it is zero, and closer it is repulsive. Sounds like a perfect
place where you need a mathematical function similar to the above for
Newtonian gravity, of the form F=f(r,M,m).  All you need to do is to
describe mathematically what the function "f" is. Then you have a crude
model, easy peasy!
