"Universes" might have an "origin" within our own intuitive misconception of time but Reality has no origin, it just is.
Relations of cause and effect which entail actual computing are a correlation in the ORDER of 4D Spacetime and thus an illusion formed in the very ordering of events which we perceive as computing or problem solving.
There is no Chaos just complexity in this Order.
There is no Randomness either just in build epistemic incompleteness to our nature as a sub set of a greater Set/Domain.
Phenomenology has an Ontological status so illusions are as Real as anything else which is at the bottom of this chain of correlations that set apart domains of "activity". The process is fractal to.
"God" is just the Order, standing as a rock, The Rock, there, forever...
...a forever which is exactly as a single nanosecond which never gets lost...a code line of information which doesn't vanish...
The number of dimensions is irrelevant to the number of fractal Qualia expressed in the multiple domains of the "Rock".
Well... I am fed up explaining Metaphysics, ya all have a nice day, I am off to playing MSFS 2020...I will pick my Cessna SkyMaster II for a ride in the Caribbeans!
