What makes you think entanglement and superposition inhabit Spacetime?

Those events scream they have nothing to do with spacetime, so why are you refusing to let them go? I say let them be their own thing, they don't work with time or gravity anyways.

I know what you are going to say:

Quantum field theory is defined on a spacetime manifold. Everything described by QFT can always be represented as a field on spacetime, even a single particle state.

A QFT is an operator valued field on spacetime. In the simplest case of a discrete lattice field, there is a Hilbert space representation of each lattice site, and the whole field is a tensor product of these Hilbert spaces, which have adjacency relations and form a simple grid over spacetime. The theory is always defined on (usually Minkowski) spacetime, there's no "floating above" spacetime.

Your answer is built on a man-made excuse/mistake to include QM in spacetime. Yes, it has math going for it, but it isn't sharing what the reality is. Spacetime is under no obligation to include the scale of QM. QM existed before the big bang: https://phys.org/news/2019-05-stabilizing-no-boundary-universe-quantum.html

Do not bring this subject up again unless you have something more than opinion to back up your claims. 

Science doesn’t care about “reality”, only what can be modelled and tested. Until you can model and test your claims, they are not science and do not belong on this forum.
