I can adapt spacetime to see smaller 2d quantum aspects which scale down quite well but the closer I get to sub spacetime in 1D then I hit the issue of there being to much hyper sensitivity in the model especial if I assume infinite dimensions of space and infinite feature scaling and that would just be a basic incomplete mathematical issue no way near the dynamic of sub space time. However from this extreme noise 1d space time emerges seen in it's effects at a larger scale.
What is really happening is that sub space time is an evolving noisy fabric embedded in god the wildest out there there is.
however I can explain a few properties of this emergence out of such fabric. the fabric is both evolving and expanding relationships with all matter shift around it's just if you re entangled somewhere else you new entanglement location would re integrate in to the parallel time distribution so it would just seem normal and you wouldn't remember the slightly different world being any different unless higher contraction occurs between aspects of 2 dynamic zones.
You could send information back in time linking into this mechanics with a very advanced quantum computer link the lottery results although once implemented it would be as if things had always been that way according to spacetime but you would have tomorrows lottery results. In terms of determination and free will this issue much considered as this dynamic super verse is evolved using god the ultimate in freewill.
however if you spin a warp drive space craft faster than light round the sun you would not go backwards in time. if you went faster than light round a warp ribbon and slung shot into non warped space you would break up and explode.
I intend to go further with this space and greatly extend attributes autonomy and structure in a sense i have already done this over further lives.
although from my perspective I can bring my moment with space to situations where reality seems fake but It would only be me backed into a corner in this very real space. I would be a fool to assume the little corner is all there is to it.
