Dear Yuri!
1. You asked me - why 12 - dimensional Space-Time? I answered you in your topic: 3 - linear 3-wave 3-vortex (Greek-dine). Therefore synthetic extended Space - is 3M (mea), but not 3D (dim).
2. Time - is the memory of material structure at a certain level of its whole being. That is his nature. Time is a burden. Time is the price of the Becoming.
3. I agree with you that the true model of the Universe is a model of Eternal Universe. Modeling of Universe must begin with one of the ancient Axiom (Superaxiom): "In the Beginning Was the Logos ...". This is the meeting point of Knowledge and Faith, Science and Religion.
4. You have the right question, the right way, but I have not found an essay ontological justification of your hypotheses.Today the fundamental physics and mathematics - not ontologically grounded science.
Sincerely, Vladimir
