Dear Eckard,
I am sorry for the delay in replying to your queries.I am also sorry for the ambiguity in my previous reply to you. It is helpful to me too, to discover these ambiguities that make my explanations less clear than they might be.I can then try to avoid them.I am glad that you brought it to my attention.
I mean by discounted, in this case, ignored. The observer is as real as the object. But the observation made by the observer is of the image not the object itself. Object as I am using it, refers to a material thing with full realism even without the possibility of direct observation.It is not dependent upon observation or conscious experience to bring it into existence. Like the magician's rabbit, it does not have to be seen to be real. So the observer perspective can be ignored when this facet of reality is under consideration.
I am using the term Object as a substitute for objective (which has the counterpart subjective.) As I do not wish to discuss in this essay only subjective human experience but a physical process occurring irrespective of consciousness. It has been argued by some quantum physicists that conscious awareness is necessary for decoherence to occur but I am saying this is not necessarily so. As there can be inanimate image reality generation. (It requires only a reality interface such as a photographic plate.)
Image, as I am using it,is a generated representation of the object. It has some similarity to the object or source of the data used to form the image. It is not formed from the same material. It could be an image on film , a sound recording, a visual experience generated by the visual cortex of the brain for example.
When we are referring to the Object reality, then a universal perspective is not necessary. Objects have actual, ever changing position, that do not rely upon frame of reference. That is the "really real" non relativistic reality. If it was possible to instantly measure distance between each particle and object as you have said A to B must be equal to B to A, it could be mapped. However such measurement is not possible.
When object and observer are spatially separated and measurements are made it is the appearance of reality, the image, that is observed not the underlying reality. There is delay in transmission of the data and a temporal distortion creeps in to the measurement. Only with an Object universal perspective could the absolute trajectory be ascertained and a non relativistic position at which an object existed in the universe be known.
We also do not have that universal perspective. Therefore we must be content with a "half way house". A super relative position which is obtained from trajectory observation of a number of observers in different frames of reference. By finding the overlap of those trajectories a position can be found that the object must have occupied in order to generate all of the different trajectory observations. The different observers are seeing the object at different times due to differences of data transmission time.
I am using the term Object universe to distinguish it from the space-time image reality universe. I has no time dimension but exists as a uni-temporal structure.
I have not yet read Basudeba's essay but will do so soon.I am also mindful that I must also re read and consider your own, Ewin Klingman's and Peter Jackson's essays.It is too much to accomplish all at once.
Best regards, Georgina
