Description
he development of a unified theory encompassing the Standard Model and General Relativity often necessitates theorizing features that violate the Weak Equivalence Principle (WEP) and/or the gravitational Inverse-Square Law (ISL). Such a violation would indicate our current understanding of gravity is incomplete. Undergraduate researchers and faculty members at Cal Poly Humboldt are performing an experiment to measure gravitational influence at ranges less than 50 microns in an attempt to identify any deviations and explore the significance such a discovery would have. Using a compositional-dipole torsion pendulum and an oscillating attractor mass, torque is created on the pendulum to study its response to the gravitational field of the attractor mass.
