Abstract

In The Effect of Light on Gravitation Attraction, published in 2011 (Rancourt, 2011), a purpose built horizontal-torsion pendulum apparatus, based on the Cavendish apparatus, was used to measure the effect of light on freely moving masses. Tests indicated a laser light on one side of a freely movable mass caused the mass to move toward the light. It was hypothesised that light has a screening effect on gravitational force.

In view of these findings the present authors designed a series of experiments using a specially designed light system to further test the effects of light on gravitation.

This paper describes a series of experiments in which layers of light are directed above and below a test mass connected to a sensitive weighing device. The aim being to determine whether light would affect weight readings.
