The Pioneer Anomaly and a Rotating G\"odel Universe

TL;DR

This paper investigates whether the rotational aspects of a G"odel universe could explain the Pioneer anomaly, concluding that such rotation is insufficient to account for the observed effect.

Contribution

It demonstrates that the rotational terms in a G"odel universe are too small to explain the Pioneer anomaly, ruling out universal rotation as the cause.

Findings

Rotational terms are too small to explain the Pioneer anomaly

Universal rotation contributes but does not account for the effect

G"odel universe's rotation is insufficient as an explanation

Abstract

Based upon a simple cosmological model with no expansion, we find that the rotational terms appearing in the G/"odel universe are too small to explain the Pioneer anomaly. Although it contributes, universal rotation is not the cause of the Pioneer effect.
