Paradox-free classical non-causality and unambiguous non-locality without entanglement are equivalent

This article title suggests a highly technical and theoretical topic in physics, likely related to quantum mechanics or related fields. The terms 'non-causality' and 'non-locality' are key concepts in these areas, and the claim of equivalence is significant. The mention of 'without entanglement' is also noteworthy, as entanglement is a central feature of quantum mechanics. The source, ArXiv, indicates this is a pre-print research paper.
