Cool!

Here's my question: Isn't the 1/r^2 just a consequence of Gauss' theorem or are you trying to look at possible extra dimensional effects here?

1/r^2 and Gauss' law are two sides of one coin.

We're looking for any deviation from that plan, in the form of new forces or a change in the behavior of gravity itself. Either one would be really cool to find, and the fact that we keep not finding anything places increasingly tight constraints on theories that attempt to extend the Standard Model or build a bridge from the SM to gravity.

Thanks for you answer and for the good work!

The biggest laurels go to John Lee and Ted Cook -- they were at the tip of the spear for a combined ~12+ years to make this happen.
