Comment from a crank on alternate theories of reality: We can do some pattern recognition, and notice a pattern:

Strong nuclear force. Weak nuclear force. Gravity. Einstein's Constant/Cosmological Constant/Dark Energy/Vacuum Energy.

Attraction. Repulsion. Attraction. Repulsion.

(Also, below that, Strong Interaction and whatever force keeps neutrons apart, sometimes stated, somewhat nonsensically in the general case, to be the exclusion principle.)

Assuming this pattern holds across all scales (and do we have any reason to believe the range of scales around the one we happen to occupy is special or unique, apart from the fact that they're the range of scales we happen to be capable of observing?), we shouldn't expect the universe to end at all, although our local universe might conceivably run out of exergy.

Your list of interactions notably omits electromagnetism, which as well as being vastly important in the physical phenomena we observe all the time happens to be neither simply attractive nor simply repulsive.

It is also incorrect to describe the weak interaction as a repulsion; as with electromagnetism its effects can be either attractive or repulsive.

I've played with formulas; I've come up with something like:

q2 * m1 * m2 * sin(sqrrt(r * C1))/(r * C2)^2

Where q2 is the charge of the nonlocal matter. (This formula calculates the force exerted on m1; the force exerted on m2 may be different.)

I suspect the actual function inside the sin may be more subtle than that. The salient point would be that the wavelength is a function of its distance, and the wavelength increases (exponentially, I think) with distance, which produces a scope-insensitive force.

I'm sorry -- what is this meant to be describing, exactly? Some already-known physical phenomenon, whose rules you think may be different from those it's currently thought to obey, or a conjectural new force?

The former. Or rather a set of phenomena which I believe to be more closely related than currently thought.

OK. Which physical phenomena do you think might be described in that way? I'm pretty sure the stuff in the Standard Model has been measured accurately enough to rule out anything much like what you describe.
