Yes! you've captured the gist and fleshed out the raw concept that "hit" me whilst reading your post on "weightless" computation; that's potentially the value of it as an avenue to explore, I think: that there is an equivalence/symmetry/correspondence by which the universe's map to one another but it's not direct(?) is it a form of information conveyance? hmmm.. Reference time...
