Measuring gravitational behavior at short distances in space: A local test for MOND/MOG

Abstract

We consider the AQUAL theory - a theory of modified gravity capable of resolving the missing mass problem - and study its predictions for micro gravity tests at the gravitational saddle points of the Solar system. We report that the AQUAL model enhances the gravity at the sub-micrometer ranges around the gravitational saddle points in a way that so far has been unnoticed. This enhancement can be measured. We, therefore, call for moving toward implementing micrometer gravity tests within the Solar gravitational saddle points.
