Hello George,
I like your way of thinking. Nice short and to the point. Geometrically seen you take only the direction as measureable phenomenon. Then there is no need for a particle while only the value of volume/density/exchange of n measureable forces interworking upon n measurable forces occupying a certain space during a given time defines the working upon and the forming of thereof arising complex forms. By which every limit of a form is a sphere of exchange und by its complexity immeasurable into definite numbers. Only approximation. Uncertainty. Like a beautiful cocktail.
A way to bypass this is partly to read in chapter 4 of my essay in this contest: http://www.fqxi.org/data/essay-contest-files/Hoebe_The_I_as_ObserverObse_1.pdf
I propose there a certain geometry by which form arises according to specific laws. These forms can only be thus and that. The basic form is 3-simplex. An important law is the law of harmony. Its gives way to beauty and that what fit well.
Taken your idea and mine together one could show the geometrical movement of phenomena all according to their volume/density/exchange of force and as force. These forces will be tetrahedral under pressure or low temperature and bi-tetrahedral when having enough space to expand in and as, and by a high value of exchangeability.
This way dark-matter could be seen as the sphere of exchange und by its complexity immeasurable into definite numbers, and its complexity is then merely the immeasurability of their sphere and size of interaction and its almost nothing-ness in density and every-ness in volume and exchange. Like you can feel yourself, but cannot pinpoint it in a location or now. Only the value of being does.
Interested?
All the best,
Jos Hoebe
