Giorgio Gratta (Stanford) "Probing Gravity – and Other Forces – at Extreme Scales"

May 5, 2016 @ 4:00 pm - 5:00 pm

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.  While the long distance regime would involve a deep space mission, a new breed of experiments focusing on the micron regime is already taking data, not only on gravitational interactions.
