Hello again, Edwin:
I took some time to review you article "Everything's relative, or is it?" I see clearly now that we are absolutely on the same page ontologically. I have focused on quantum mechanical issues and was unaware of the issues regarding relativity that you raise. SR clearly allows different frames of reference (FORs) to synchronize their clocks if their relative motions are zero. If we assume a stationary FOR, we can therefore define a universal time frame throughout 3D space. 4D spacetime and 3D space time are distinct conceptual models with distinct mathematical descriptions, which you have detailed. I was interested to learn that within the 4D spacetime ontology, length contraction is implied, but it is not empirically observable! We have both argued that a valid empirical model can accommodate multiple conceptual models, but only one is right. We both agree that physical reality must be defined with respect to its actual physical framework, or more generally, to its context.
I hope you take a closer look at my essay. If you overlook my lack of appreciation of different ontological interpretations of relativity, you will find a deeper framework that unites our contextual conceptual interpretations. By including a positive ambient temperature as part of the context, I eliminate quantum paradoxes, establish the 2nd Law of thermodynamics as a fundamental physical law, and allow an objective definition and arrow of functional complexity. A positive ambient temperature is empirically justified because absolute zero is an idealization that does not exist in reality, and the universe as a whole has an ambient temperature currently equal to its 2.7 K cosmic microwave background.
Thank you for expanding my horizons. I hope I can return the favor.
Harrison
