Any nonlocal model assuming "local parts" conflicts with relativity

TL;DR

The paper argues that nonlocal models with local parts conflict with relativity and can be replicated by multisimultaneity, implying space-time structure necessitates influences beyond space-time itself.

Contribution

It demonstrates that nonlocal models with local parts are incompatible with relativity and can be simulated by multisimultaneity, highlighting the need for influences outside space-time.

Findings

Nonlocal models with local parts conflict with relativity.

Multisimultaneity can reproduce these nonlocal models.

Space-time structure requires influences from outside space-time.

Abstract

It is argued that any nonlocal model producing "local parts" (i.e.: disappearance of the correlations under certain testable conditions) can be reproduced by "multisimultaneity" and therefore (because of arxiv:1304.0532) conflicts not only with quantum mechanics but also with relativity. This result means in particular that the very structure of space-time (relativity) requires influences coming from outside space-time.
