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

TL;DR

This paper discusses the implications of quantum nonlocality and free will, arguing that these features are incompatible with the many-worlds interpretation of quantum mechanics.

Contribution

It presents a philosophical argument linking nonlocality, free will, and the incompatibility with the many-worlds interpretation.

Findings

Bell's inequality violation implies nonlocality

Nonlocality and free will are incompatible with many-worlds

Recent experiments support nonlocal correlations

Abstract

Observing the violation of Bell's inequality tells us something about all possible future theories: they must all predict nonlocal correlations. Hence Nature is nonlocal. After an elementary introduction to nonlocality and a brief review of some recent experiments, I argue that Nature's nonlocality together with the existence of free will is incompatible with the many-worlds view of quantum physics.
