Dear Jim Stanfield,
interesting essay, although with some leaps of faith in it in my opinion. I like your description of the rubber sheet, which shows that spacetime, if continous, must be very twisted at the lower scales because all that has mass contributes to its shape.
I am not entirely sure whether you take mathematics as a platonic realm or as something that was created (surely before physical things were created) along a certain process.
By taking the empty set as some kind of first cause, you tacitly have inserted what you want to show: the duality of an empty set does enable a self-creation process. But this seems to me to be only true (if at all) under the assumption that maths and moreover logics is somewhat already there. Furthermore you make a twist to arrive at your polarity: the abstract existence of nonbeing. It seems to me that this is just an a posteriori view from the point of view of an observer who operates logically due to what he has observed. An empty set at the beginning 'of it all' does not differentiate between the abstract existence of nonbeing and being (the latter you obviously have identified with the empty set as the abstract being-part).
So, we have to 'nothingnesses', one is the empty set (the abstract being), the other is all that is not included within the empty set (means outside of it, the abstract nonbeing). I think these two nothingnesses are only differentiated linguistically. If in the empty set there would be some property that this set leads to being and outside this set there is the lack of this property, then the 'empty set' cannot anymore considered to be empty. It has some additional property (besides the fact that it abstractly exists).
What you need is some kind of pre-existing logic which discriminates between what is possible (what can exist) and what can't exist. Because your empty set is devoid of logic, it equals what has been termed 'nothingness' and traditionally understood by it. True nothingness not even contains an empty set, it is devoid of any meaning, logics, rules and potentiality. This is the reason why you can't comment on what qualifies mathematics to generate physical substances other than assuming it by taking it for guaranteed that mathematics (abstract relationships) have the fire within them to instantiate themselves somehow. Your empty set, even though tought of as a kind of polarity, cannot create anything further because it is devoid of any transcendental meaning. For modeling such a creation process, you need an 'empty set' which is only defined as empty relative to our experience of 'something' *and* relative to our logic which operates mostly in dual terms (means, in the modus of antivalent logic).
The phase transition from the abstract to the physical is unclear to me. You make your case with some kind of string theory, but i think with that you slowly loose the path and take speculations as realities due to the presupposed firepower of mathematics (the latter having been inserted into maths by you some lines of reasoning before).
The square root of -1, in my opinion, is an expression of taking a non-mathematical statement into the equations to proceed with a mathematical description of reality. Insofar it is an inconsistence to take the square root of -1 as a mathematical entity. It is just an expression of the fact that logics can transcend its limits of deducability such that it must induce that its origins must be located out of itself. Logics cannot have logically produced itself, and neither can mathematics via an empty set. Either these abstract structures are an accident in a lawless, unknown nothingness, or they are necessary due to some higher purpose (higher logic in the sense of an intelligent being which intentionally has created the landscape of mathematics and our world [both by a process of separation]). I think the square root of -1 speaks for the latter case. This higher logic could be in my opinion a synthetical a priori. Its existence is further obvious to me when pondering about logics itself. I think there are good reasons to assume that logics is consistent, but incomplete (in the sense that there must be a higher logics).
Best wishes,
Stefan Weckbach
