A-G, what I'm wondering is whether the primary field of universal consciousness/primary substrate of natural being may be virtually outside of human space-time altogether. Yet still very much within the scope and range of human intelligence....
To me, this is a perfectly mind-boggling idea.
By the way, I dutifully read the two articles you pinged me to. I enjoyed "Constraints on Extra Time Dimensions" very much. I definitely noticed how the authors decided to "file-off" something they had seen as belonging to a hypothetical "time-brane" -- an additional hypothetical time dimension beyond the 3S + 1T four-dimensional space-time that we human beings are steeped in since birth -- to account for certain inconvenient "leakages" from the matter side of physics. (I gather.)
I was also very intrigued by the authors' analysis of "gravitational self-energy." Good grief, I didn't realize that issues relating to the propagation of charges remain such open questions today. The implications for integrating gravity into any Unified Field theory must be staggering in consequence.
Also read that other paper. It definitely left an impression on my mind, even though it really was written for initiates into the mysteries of string theory. I will not bore you with my take on this (taxpayer-funded!) enterprise, unless you hold hot coals to my feet! LOL!
BTW, I think Grandpierre handles these issues with consummate insight and grace. Which is more than I can say for the publicly-funded crowd that, these days, gives us works like "Evidence for F-Theory."
The paper falls short of its own initial abstract: It does not explain the cosmological constant; and it does not explain, or "pictorialize," any type of "interface" between string theory and macroreality.
What it tells you is: Do further experimentation. Put F-theory right up there with two other fundamental constructs, and you've got a real shot at solving all the problems of the universe some time soon.
And by the way, keep those government grants coming meanwhile....
IMHO, they will find the answer to the quantum riddle in geometry. And that answer will come not from quantum mechanics but astrophysics - cosmology and astronomy!
