Tests of Short-Range Gravity with a Novel Parallel-Plate Torsion Pendulum

Michael Powers Ross

Abstract


The incompatibility of the Standard Model and General Relativity has pushed gravitational measurements to the forefront of experimental physics. The general lack of short range gravity measurements has inspired students and faculty at Humboldt State to construct an apparatus that will measure the effects of gravity at submillimeter scale. This experiment will consist of a torsion pendulum in a parallel plate geometry with an attractor mass that will oscillate in close proximity. Since our previous report, [1] the apparatus has entered into the commissioning stage and has begun to take preliminary data.
