Abstract
Gravity has been tested rigorously at distance scales from 1cm up to astronomical distances. The experiment being run in Humboldt State Universities Gravity Lab seeks to test gravity at previously untested distances below the centimeter level. To do this, a pendulum is suspended by a torsion fiber and oscillates in front of a movable mass. By moving the mass back and forth, one can measure a gravitational force on the pendulum by looking at the twist in the fiber. The data from the pendulum are then compared with well established theories of gravity to see if the accuracy of the theories at large distances translates to smaller scales.
