Abstract

Motivated by higher-dimensional theories that predict new effects, we tested the gravitational 1/r(2) law at separations ranging down to 218 microm using a 10-fold symmetric torsion pendulum and a rotating 10-fold symmetric attractor. We improved previous short-range constraints by up to a factor of 1000 and find no deviations from Newtonian physics.

摘要

受预测新效应的高维理论的推动，我们使用一个十重对称扭摆和一个旋转的十重对称吸引体，在低至218微米的间距下测试了引力的1/r²定律。我们将之前的短程限制提高了多达1000倍，并且未发现与牛顿物理学有偏差。
