Description
Attempts to unify the Standard Model and General Relativity often include features that violate the Weak Equivalence Principle (WEP) and/or the gravitational Inverse-Square Law (ISL). A violation would question our understanding of gravity. To further understand this, undergraduate researchers and faculty at Humboldt are experimenting to measure gravitational interactions below 50 microns. The experiment uses a composition dipole torsion pendulum next to an oscillating mass. This creates torque on the pendulum, the magnitude of which may provide evidence for deviations in the WEP or ISL.
