Some of the more...poetic...parts of your posts I don't really follow. Obviously I can't evaluate your subjective experience of the universe because "subjective" -by definition- is specific to you (or me, or Gh, or anyone else). But "boundlessly eventuating infinite potential" doesn't really convey any meaning to me.

I see all of experience as evolving within what many scientists regard as an original singularity boundlessly emergent within erstwhile nothingness.

Needlessly poetic, but it appears you are saying that all experience within this universe is contained within this universe that began as a singularity expanding into nothing. Which, to the best of my knowledge, is reasonably accurate as far as it goes. Though we can't prove that we're expanding into nothing, or into something. And maybe we never will be able to prove it. Not unless we can figure out how to enter/cross dimensions that we can't even perceive, assuming those dimensions are even there.
