The zero-point energy of elementary quantum fields

TL;DR

This paper reviews seven arguments regarding the zero-point energy of elementary quantum fields, concluding that the arguments against its divergence are significantly stronger than those supporting it.

Contribution

It provides a comprehensive assessment of all existing arguments for and against the zero-point energy divergence in quantum fields, clarifying their relative strengths.

Findings

The contra arguments are overwhelmingly stronger than the pro arguments.

The paper clarifies the debate on zero-point energy divergence.

It suggests reconsidering the assumption of diverging zero-point energy.

Abstract

Since 1925, exactly four arguments have been forwarded for the assumption of a diverging (respectively --- after regularization --- very huge) zero-point energy of elementary quantum fields. And exactly three arguments have been forwarded against this assumption. In this article, all seven arguments are reviewed and assessed. It turns out that the three CONTRA arguments against the assumption of that zero-point energy are overwhelmingly stronger than the four PRO arguments.
