Now, I'm confused as I always thought that with respect to the ontolgy of space-time there were only two options:

1. Relationist: space and time could not exist without matter.
2. Dualist substantivalist ("container/bucket"): spacetime is the container/bucket and material objects are the contained (objects in the container).

With (1), if you remove matter there's "nothing" left. With (2), if you remove the objects the bucket/container/empty set still remains. But apparently there's a third option:

3. Monist substantivalist: There is no need for the dualism of the container and the contained (or for fundamental containment relations):

So I'm guessing that in this third ontology, if one removes that "one" stuff, nothing should remain? But what about stuff that may not be described as propagating in space-time like quantum correlations? Gisin has argued that:



Quantum nonlocality based on finite-speed causal influences leads to superluminal signaling

Are There Quantum Effects Coming from Outside Space-time? Nonlocality, free will and "no many-worlds"

I mean, if stuff like these quantum correlations defy spatio-temporal descriptions, it seems that all 3 views are somehow flawed? Although I'm guessing the relationist view would still be safe?
