On the Geometrical Character of Gravitation

TL;DR

This paper critically examines whether quantum phenomena suggest non-geometrical aspects of gravity, concluding that current evidence does not support a departure from gravity's geometrical nature.

Contribution

It provides a critical analysis of previous claims about non-geometrical aspects of quantum gravity, reaffirming the geometrical character of gravitation.

Findings

No current evidence of non-geometrical gravity in quantum phenomena

Clarification of interpretational issues in quantum mechanics related to gravity

Reaffirmation of the geometrical nature of gravitation

Abstract

The issue of whether some manifestations of gravitation in the quantum domain, are indicative or not of a non-geometrical aspect in gravitation is discussed. We examine some examples that have been considered in this context, providing a critical analysis of previous interpretations. The analysis of these examples is illustrative about certain details in the interpretation of quantum mechanics. We conclude that there are, at this time, no indications of such departure from the geometrical character of gravitation.
