We conducted three torsion-balance experiments to test the gravitational inverse-square law at separations between 9.53 mm and 55 microm, probing distances less than the dark-energy length scale lambda(d)=[4 -root](variant Planck's over 2pic/rho(d) approximately 85 microm. We find with 95% confidence that the inverse-square law holds (|alpha|<or=1) down to a length scale lambda=56 microm and that an extra dimension must have a size R<or=44 microm.
我们进行了三项扭秤实验，以在9.53毫米至55微米的间距下测试引力平方反比定律，探测小于暗能量长度尺度λ(d)=4 - 根号约85微米的距离。我们有95%的把握确定，平方反比定律在长度尺度λ = 56微米以下仍然成立(|α|≤1)，并且额外维度的大小必须满足R≤44微米。
