Novel Tests of Gravity Below Fifty Microns

Due to the incompatibility of the Standard Model and General Relativity, tests of gravity remain at the forefront of experimental physics research. At HSU, undergraduates and faculty are developing an experiment that will test gravitational interactions at the twenty-micron distance scale, well below what has currently been tested. The experiment will measure the twist of a torsion pendulum as an attractor mass is oscillated nearby in a parallel-plate configuration which will provide a time-varying torque on the pendulum. The size and distance dependence of the torque variation will provide means to determine deviations from accepted models of gravity on untested distance scales.
