Fascinating, MHGinTN! Trying to imagine what the quantum world looks like is an amazing exercise. Did I read on another thread that you suspect there are 7 dimensions? Do you see this as a hierarchical arrangement?
Myself, I don't know how many different types of fields there are, but I suspect whatever number they may be, they are intimately coupled in some fashion. As for the number of dimensions, I think there may be 5: 3 of space plus 1 of time - 4D space-time; and a 5th, which is temporal....
But who knows, really? I mean, how would we go about verifying our conceptions? Still, it's great fun to speculate! Thanks so much for writing!
As you know, I am keenly interested in Geometric Physics!
I assert that the duality of space/time and gravity is not a fluke any more than wave/particle duality is a fluke. The mirror imaging is the point of Vafa’s article linked above.
Your speculation of an extra time dimension really captured my attention, betty boop, and as you know has been the framework whereby I now see potential solutions for a host of issues in physics and philosophy. I was delighted to discover that Vafa is exploring extra time dimension theory at great length!
It has been presumed for many years that the extra spatial dimensions would be curled up into tiny vibrating strings (string theory) based on Kaluza-Klein compactification. I believe you agree with me that this is not a necessity for extra dimensions and the alternative non-compactified theory has much greater explanatory power.
As a final point, I would like to suggest that observation and research concerning dark energy to explain the acceleration of the universe may result in the best evidence for extra time dimensions.
