What is it? Is there a Path Integral that is valid for a Particle and the detection device's, such as Observers? In General Relativity, events are deemed to be real at 'local' co-ordinates. If one looks out up into the night Cosmos, 'reality' tends to "fade" with distance, distance is scaled to size over distance. Now if one looks inwards, down into events from 'local' time events, down into Quantum Domains, then events also tend to fade away from reality , but with scale to size over distance, having no continuity. If observation, or specifically observers are the gauge of reality, the continuous direction one face's in observation, should have a 'reality' cut-off be-it, if one looks outwards, or if one looks 'inwards'. If a projectile is launched outwards into the Cosmos, if it continues away for some distance, then it should become less 'real', it should behave with the same traits as that for a Particle that is deemed to be crossing from the Local Event space, GR into the Quantum un-event domain. Question, is the Universal Horizon at a far off distance, a 'hidden variable' a virtual quantum event frame?
