Bell's Theorem, Many Worlds and Backwards-Time Physics: Not Just a Matter of Interpretation

TL;DR

This paper compares interpretations of quantum mechanics, highlighting how Bell's Theorem constrains objective reality, locality, and causality, and discusses empirical evidence favoring many-worlds over Copenhagen, along with backward-time physics theories.

Contribution

It analyzes different interpretations of quantum mechanics, emphasizing empirical support for many-worlds and exploring backward-time physics models.

Findings

Empirical evidence favors many-worlds interpretation over Copenhagen.

Backward-time physics offers alternative explanations consistent with Bell's Theorem.

Discussion of quantum measurement and condensed matter representations in different interpretations.

Abstract

The classic "Bell's Theorem" of Clauser, Holt, Shimony and Horne tells us that we must give up at least one of: (1) objective reality (aka "hidden variables"); (2) locality; or (3) time-forwards macroscopic statistics (aka "causality"). The orthodox Copenhagen version of physics gives up the first. The many-worlds theory of Everett and Wheeler gives up the second. The backwards-time theory of physics (BTP) gives up the third. Contrary to conventional wisdom, empirical evidence strongly favors Everett-Wheeler over orthodox Copenhagen. BTP has two major variations -- a many-worlds version, and a neoclassical version of partial differential equations (PDE) in the spirit of Einstein. Section 2 discusses quantum measurement according to BTP, focusing on how we represent condensed matter objects like polarizers in a Bell's Theorem experiment or in tests of Hawking's cosmology. The Backwards Time Telegraph, though speculative, is discussed.
