No we do not have to as they have already taken that into account:

Ball in Fork of Tree Moves in Relation to Ground But Not in Relation to Fork

Q.A ball rests in the fork of a branch of a tree. The player climbs the tree to play his next stroke. The branch bends under his weight. Although the ball has moved relative to the ground, it has not moved relative to the fork. Is the ball deemed to have moved?

A.The ball is deemed not to have moved since it did not move in relation to the fork of the tree in which it was lodged.

Yes, but what if the ball remains stationary but the spacetime between the ball and the cup curves due to the presence of a large mass (say, from a very dense golfer walking by)? Presumably you must then replace your ball, but I am confused as to how to choose a point of reference for this, since all inertial reference frames are equivalent.

Now that Higgs boson has been found, I guess R&A; and USGA can implement all this into next revision of rules. Or if needed in meantime, release some Decisions.

So if my ball is in the sand, do I give myself the penalty for grounding my club because from quantum mechanics the position of my club is not fixed but extends in a probability density function throughout everywhere,  my wedge was "grounded" to the sand even when it was in the trunk of my car.

Or are you recommending that I disregard the Rules of Physics?  Mulligan city?
