Abstract
A test of Newton’s inverse-square law of gravitation by Eckhardt, Jekeli, Lazarewicz, Romaides, and Sands using gravity measurements on a tall tower yielded evidence for non-Newtonian gravity. We have refined the analysis of that experiment by including detailed topographic information and conclude that, in fact, no such evidence exists. The accuracy of the experiment constrains the Yukawa-potential coupling constant α to be less than 0.001.Keywords
