Your last post here is beautifully worded. It hits right to the point of the philosophical thinking, of why do we need to reduce further from what we already know about the fundamental aspects of our universe. Those being, as you state and I agree with, particle, motion, and space.
I have read what you have said in your post three times now, because it so begs for a reason to go further in to the realm we do not know of. The reason to go further is, that the answer to the need for life is tide to the reason or cause for the universe to come into existence. Yes it is fine to stop at the basic fundamentals of the universe for everyday life. But, for those of us that want to seek the great why, most have the strength climb over that peak of the mountain, that hides our view of the beginning.
If you look deeper into my theory you will see that I say this universe popped into existence from an infinite Paradox of Potential. You will see that "Aware" having no medium to exist in, but itself, created its own volume by going in upon itself. This creating of volume was not intentional, it only was the continuation of direction from being "popped". This volume is only relative to its own existence. My singularity is only the point in this volume where creation of this volume ends and "Aware" waves back upon itself, adding motion and purpose to its existence.
You asked if I was trying to reduce to a singularity. My answer is, no. There are enough people trying to do that. I do not go back, I start from an infinite potential, that a volume popped into, that is influenced by a wave of will that started at the singularity of the volume of a sphere.
