Dear Christi
I've just re-read your essay and congratulate you, though areas were outside my more conceptional and empirical approach. In particular I reconsidered in a broader sense your 'boxed' comment;
"The best evidence for the continuity of reality would be provided by a theory which is based in an essential, irreducible way, on the necessity that spacetime and the values of the fields are divisible ad infinitum."
I realised that this is at face value entirely equivalent to the model of discrete fields which I describe, itself also consistent with Edwin Klingmans Cfield. Your route otherwise is largely finer than my 'overview' approach, and would not be qualified to comment. My discrete fields are consistent with Einstein's descriptions, applicable from a single ion up to the (or each) universe where in relative motion.
I've just posted a logical assessment of where it derives SR may reconnect with it's quantum mechanism, where GR also more naturally emerges. I am not a mathematical physicist but a logician and architect, viewing the matter from a different place, and that job is done. I really hope you're able to read and comprehend the dynamic variable logic in the style written.
I feel it is important, and your views would be appreciated, if you have the time and am not suffering the eye strain I am!
Many thanks
Peter
