In terms of the unknown laws of physics -- oh, they're out there somewhere. But, and here's the catch, those unknown laws of physics will also have to replicate, or contain, our current understanding when it's appropriate. Put simply, the model that's expressed in my avatar is too good to be entirely wrong. It's incomplete, certainly, but fits and describes the world as we measure it too a stupendous degree of accuracy.
So any new physics would have to extend, rather than replace, the current state of understanding. As far as I can tell such effects as dowsing, or general psi phenomena, would replace rather than extend modern physics.
