Variations of G and SEE project

TL;DR

This paper discusses the challenges in measuring the gravitational constant G and proposes a new universal space project aimed at significantly improving measurement accuracy by 2-3 orders of magnitude.

Contribution

It introduces a novel space-based project designed to enhance the precision of G, G(r), and G-dot measurements beyond current capabilities.

Findings

Discussion of experimental and theoretical issues in G measurement

Proposal of a new space project for G measurement

Expected improvement of 2-3 orders in measurement accuracy

Abstract

Problems of absolute G measurements, its temporal and range variations from both experimental and theoretical points of view are discussed, and a new universal space project for measuring G, G(r) and G-dot promising an improvement of our knowledge of these quantities by 2-3 orders is advocated.
