Spacetime is a vector in Hilbert space. Entanglement yields locality. Space emerges. I'm not convinced time is emergent, though (I give the idea low credence).

I'm not a scientist, I just listen to Sean Carroll's podcasts.
- bitcharmer 6y ago> Entanglement yields locality Could you please expand on that?
- slowmovintarget 6y agoIn trying to derive spacetime from quantum field theory, some working theories show that minimum "energy" fields that are highly entangled with each other are "near" each other. That gives you locality, therefore space. That is, locality arises in the model from certain kinds of entanglement.
