Quote:"One of the biggest obstacles has been that general relativity and quantum mechanics treat time very differently. In the former theory, time is another dimension alongside space and can bend and stretch, speed up and slow down, in different circumstances. Quantum theories, however, usually assume that time is set apart from space and ticks at a set rate. Theories of indefinite causality tackle this mismatch head-on, by questioning what time is at a fundamental level." From the article 'cheating the Causal Game'.
This is nux of various problems. Understanding -Why that difference- in how time must be treated, is helpful in seeing the direction from which a solution to a number of problems must come.There are two different things going on simultaneously. Atoms are interacting and giving a causal order of events in the material Object reality and EM potential sensory data is being generated with the potential to give a different apparent order of events in time because of data transmission and processing delays.
It was interesting to read about this promising research. I don't know exactly what they are doing from such a brief article but I wonder if considering the mismatch of causality at the quantum level and apparent causality at the macroscopic level will give the gravity solution. I will outline why I think it may not.
In GR the observer is assumed to be static. That is just a subjective view. It is built into the curved space-time hypothesis and model. However the observations with which curved space-time fit, seemingly verifying the model, might instead be due to curvature of light paths resulting from disturbance of the Object reality environment, through which they pass, by motion of the body within it and through it. The description of that motion within the 3n+1 space-time construct is bizarre, not because the motion is bizarre, but that the observer-subjective construct has not been constructed in such a way that it allows illustration of what is happening. I.e. As the observer is assumed to be static, when it is not, the necessary motion can not occur within the subjective observed space but occurs instead along the time dimension. Each new observation is conducted from within a new objective space from which data is received and from which the image of the universe is constructed.
A stationary observer on the Earth is not static at all but moving with all of the Earth's movements, over many scales of possible consideration. With the galaxy, with the solar system around the sun, around its axis and with geological movements. A change in the movement of the Earth over those different scales could give a change in the apparent expansion of the Image universe if it gives a increase in the rate of movement away from the origin source of the sensory data from which the universe Image is constructed. Such changes could occur as a result of the changing motion of the material solar system or Earth due to altering, rather than permanently fixed, relationships and that will alter the 'selection' of the potential sensory data received, giving not just the affect of expansion due to the motion but increasing expansion if change in the motion is also occurring.
At the smallest scales of consideration the vibration of the particles becomes significant. The affect of that upon the environment will mask any minute gravitational interaction that might otherwise possibly be detected; and the larger scale (Object) universal movement is not included in consideration. Though subatomic particles too must be moving with the motion of the laboratory on the Earth's surface and so along with the Earth's total Object universal motion. The subatomic scale of matter is not separate from the macroscopic scale of matter but contained within it and it all moves together. That's what unites gravity over different scales IMHO.
