What we call the weight or mass of bodies is merely the locations where affectance has become extremely dense. Spreading out from such locations the density of the affectance rapidly diminishes such as to appear as mere vacuum. The gravitation and weight concepts have relevance to us, so we measure those values as if mass bodies were pulling at each other across the relative vacuum between the affectance concentrations (the bodies). So in RM:AO weight exists merely as a value that can be calculated, as does mass, but they are not individual entities or necessary properties. It is like calculating an average value. The average value doesn’t exist as an actual entity or even an actual quantity, but it is still important to calculate such things.
The effect that we call “gravitation” aberrantly exists. But there is no force that is causing it. Rather it is due to the migration of the ever-replenishing concentrations. What we call “weight” is just another term for gravitational pressure.
It is conceivable that one could alter the ambient affectance field between two mass objects in such a way as to cause them to become weightless with respect to each other, no longer migrating toward each other, and neutralize the gravitation. And it is also conceivable that one could alter that field to cause the masses to migrate more strongly, increasing their relative weight. The weight of the masses is entirely dependent upon the affectance field surrounding the masses. And that field can be manipulated, although it takes a lot to get it done. I can explain the principle for causing weightlessness, but making something that can actually do it is a lot trickier.
