When you add spacetime to QFT it becomes a model to describe a particle in duality mode.
Quantum weirdness events are not real/physical. Spacetime makes things real/physical.
I think entangled waves are seen as a single entity to the virtual field. The opposite spin is a polarizing snap. Once one is observed, they are no longer entangled. I suspect if one is to be observed in its flight, they exit the BBO as collasped waves ..physical particles.
Uncertainty is only when the Virtual Field has influence.
Cosmic voids are mostly the virtual realm. It has something to do with why they are the only spots expanding.
I don't think spacetime expands so the universe starting as a tiny dot probably isn't right. I would guess the volumes of all the galaxies where closely neighboring each other filled with plasma. And then floated away from each other.
Quantum weirdness events are a wave only activity. Spacetime turns them physical after wave collapse. Duality is when spacetime and the virtual realm are both influencing a particle. You don't get quantum weirdness events in this case.
