Because observations of the cosmos has indicated far more mass than can be easily explained by the observed material it has been necessary to plug in an additional value that has been named ‘dark matter’. I have additional concerns regarding the actual correctness of our models, but these do not seem likely to be sufficient to actually eliminate the need for the corrective value.
If we then accept the existence of dark matter, the next important question becomes ‘what exactly is it?’ The obvious candidate is free neutrons.
We presently know that neutrons carry slightly more mass than a proton and that the impressed local curvature is effectively that of gravity itself. This immediately begs the question of the actual nature of the impressed curvature. We actually do not know. We need to find a way to run experiments in which neutrons act on each other and the local curvature can be measured.
My first conjecture is that the force is gravitational in magnitude but repulsive. This has the immediate advantage of explaining why we are not buried in the stuff. In fact it tends to leave gravity wells in general.
However, without been bound to other such particles it cannot form its own gravity wells and simply moves to regions of fairly minimal curvature. Recall the natural short range of gravity itself and its geometric dependence for building such a well.
I want to observe that the close local curvature of the neutron is not neutral at all and is similar to that of a proton. We are dealing with net curvature at a remove where local geometry ceases to be a factor.
We can make the additional conjecture that the present neutron - proton balance is caused by the sorting power of the gravity well itself and for that reason distorts the observed mass balance of the cosmos.
The neutron itself is an assemblage of fundamental particles (note that I have a lot more to say on the subject) maintaining complete geometric symmetry. This has recently been observed with imaging technology. A proton has lost a particle equivalent to an electron and has a disturbed symmetry generating strong curvature effects. (let’s leave it at that for now). The free neutron on its own generates an impressed curvature but the net result is a small negative gravity like effect.
Curiously, this is important. It strongly suggests that the combination of proton and neutron may be necessary to produce positive net gravitational curvature. I had already come across hints of this in some of my theoretical deliberations which clearly provide for the possibility.
I remind my readers that the current theoretical framework fails to properly deal with gravity.
