Eternalism and Everettian Quantum Mechanics

TL;DR

This paper argues that eternalism and Everettian quantum mechanics are strongly analogous, both positing the reality of multiple times and worlds, and are compatible frameworks for understanding temporal reality.

Contribution

It establishes a conceptual analogy between eternalism and Everettian quantum mechanics, showing their compatibility and mutual reinforcement in explaining the nature of time.

Findings

All times are equally real in eternalism, similar to all worlds in Everettian quantum mechanics.

Eternalism and Everettianism are compatible and mutually supportive frameworks.

There is no unique present, as all times and worlds exist equally.

Abstract

This paper shall explore the conjunction of eternalism and Everettian quantum mechanics. It shall be argued that there is a strong analogy between these two views. In case there is an indefinite number of worlds and observers that are all equally real, there should be an indefinite number of local times which are all also equally real. Whereas Everettianism, specifically the diverging version, treats actuality indexically, relativistic eternalism treats tense indexically. All times exist analogously to all isolated Everettian worlds. There is no unique 'now' that cuts throughout all that physically exists. Instead, as eternalism propounds, all times exist. The paper concludes that eternalism and the many-worlds interpretation are not only compatible but complement each other, providing a coherent framework for understanding the nature of temporal reality.
