Interior Solution Gravity Experiment

Abstract

For practical and historical reasons, most of what we know about gravity is based on observations made or experiments conducted beyond the surfaces of dominant massive bodies. Although the force of gravity inside a massive body can sometimes be measured, it remains to demonstrate the motion that would be caused by that force through the body’s center. Since the idea of doing so has often been discussed as a thought experiment, we here look into the possibility of turning this into a real experiment. Feasibility is established by considering examples of similar experiments whose techniques could be utilized for the present one. PACS 04.80.Cc { Experimental tests of gravitational theories.
