The Australians who did the original work, Frank Stacey of the University of Queensland in Brisbane and his collaborators, had found that in the mines, Newton's universal gravitational constant appeared slightly larger than the value determined by centuries of measurement in laboratories.
where T is the stress energy tensor, G is the Einstein curvature tensor and G is the universal gravitational constant. He notes the very large value of the proportionality constant.
