Give quantum mechanics a chance: use relativistic quantum mechanics to analyze measurement!

TL;DR

This paper argues that using relativistic quantum mechanics allows for a more conventional analysis of quantum measurement within a single-world framework, challenging the reliance on Everett's Many-Worlds interpretation.

Contribution

It demonstrates that modern relativistic quantum theory can reframe measurement analysis without resorting to multiple worlds.

Findings

Relativistic quantum mechanics enables conventional measurement analysis.

The old quantum mechanics framework persists despite newer theories.

Bell's criticism of Many-Worlds did not influence the acceptance of traditional quantum theory.

Abstract

At the time of publication of H. Everett's Relative-State Formulation (1957) and DeWitt's Many-Worlds Interpretation (1970), quantum mechanics was available in a more modern and adequate version than the one used by these authors. We show that with the more modern quantum theory, quantum measurement could have been analyzed along more conventional lines in a one-world cosmology. Bell criticized the Everett-DeWitt theory quite sharply in 1987 but this seems not to have affected the acceptance of the old quantum mechanics as the framework for analysis of measurement.
