Quantum mechanical retrocausation? Call for nonlocal causal models!

TL;DR

This paper proposes a new form of multisimultaneous causality and discusses experiments to distinguish it from quantum retrocausation, emphasizing the importance of testing quantum mechanics against various nonlocal causal models.

Contribution

It introduces a novel multisimultaneous causality framework and explores experimental approaches to differentiate it from quantum retrocausation.

Findings

Proposes a new multisimultaneous causality model

Discusses experimental methods to test causality models

Highlights the importance of testing quantum mechanics against nonlocal models

Abstract

A new possible version of multisimultaneous causality is proposed, and real experiments allowing us to decide between this view and quantum mechanical retrocausation are further discussed. The interest of testing quantum mechanics against as many nonlocal causal models as possible is stressed.
