The inverse square law of gravity has been empirically tested to various degrees for distances between <0.1mm to 1AU. Outside this range very little is known and, yet, physics beyond the standard model may actually introduce new long-range forces that would be observed as anomalies in the 1/R^2 behavior of gravity. I will discuss some new experiments designed to substantially advance our knowledge in this area, at the two extremes of the distance range.
