Submillimeter tests of the gravitational inverse-square law
Submillimeter tests of the gravitational inverse-square law
Motivated by a variety of theories that predict new effects, we tested the gravitational ${1/r}^{2}$ law at separations between 10.77 mm and $137\ensuremath{\mu}\mathrm{m}$ using two different 10-fold azimuthally symmetric torsion pendulums and rotating 10-fold symmetric attractors. Our work improves upon other experiments by up to a factor of about 100. …
