Hi Heinrich, thank you for reading and the questions.
The objects of the Object universe are not differentiated by observations but by their being/happening differently from the undifferentiated.That difference does not have to be observed to exist/happen. The configuration of objects, and its change,is independent of observation. In contrast: Measurable variables are relational and not sole properties of the objects. They relate to the orientation, motion, and location of another object that might be considered. For example, rotation of an object is not clockwise or anticlockwise as such a singular attribute requires the location from which the determination of direction was chosen. Without the 'relative to' reference object, the object of interest does not have a singular orientation of rotation. Tying that in with QM, it could be said that unobserved it is in a superposition of both states. Until the way in which it will be looked at is applied and a singular state outcome is recorded. Which is not now the state of the 'Object reality' but a limited fixed state 'Image reality', a product of observation. What has happened corresponds to decoherence in QM.
The Object universe itself might be said to be dark, as in un-seeable. The illuminated objects we see are visual products of the sensory system or device used to observe them. The illumination is due to light intensity (quantity of photons) being processed into brightness of the image. Not being seen is not the same as not being there, as you will know from stubbing your toe in the dark. It is not the same as void or nothingness.
I hope I have explained how the independent state of existence or being/happening fits into physics as the missing ingredient that can make sense of the physics of the unseen at the smallest scales of investigation. It is not an immature model. Kind regards Georgina
