The ''Telephone Game'' Effect in Modern Gravity Research

TL;DR

This paper discusses how recent gravity research has overlooked the fundamental equivalence of key theories, leading to redundant studies that do not acknowledge their derivation from General Relativity.

Contribution

It clarifies the equivalence among the Trinity of Gravity theories and highlights the misinterpretation in recent nonmetricity gravity studies.

Findings

Many studies on modified gravity neglect the fundamental equivalence with GR.

Research often investigates STEGR/GR without proper acknowledgment.

Results from modified theories can be derived from General Relativity.

Abstract

Triggered by some recent studies within the framework of nonmetricity gravity, I discuss how the basic information regarding the equivalence of the gravitational theories forming the \textquotedblleft Trinity of Gravity\textquotedblright\ has been lost in parts of the literature. As a result, several studies with focus in modified theories of gravity have research investigated the case of STEGR/GR, often without acknowledging this fundamental equivalence or recognizing that their results can be derived in GR
