I have an odd theory, nothing to back it up really, but here goes -- what if "dark matter" tends to drift in and out of normal matter, doesn't interact, isn't detectable by any means except by its actual mass. I have not heard of any other theories that make any more sense than this to explain this phenomenon.
If it doesn't interact except by gravity, then it can't make a particular object heavier compared to others. Think about it. What is an solid object? A solid object is a collection of atoms bound to each other by inter-molecular forces. If dark matter doesn't interact other than through gravity, it can't make one object heavier.
Dark matter *could* make all objects heavier. You can imagine dark matter accumulating in the same place where the earth is, by gravitational attraction. So the gravitational constant of the earth would be increasing. But this would make *all* replicas of the kg heavier and we would not see a divergence. Ok, we might see a linear divergence where the lighter replicas (remember, no two can be 100% exactly the same) become lighter compared to the heavier ones, in a linear fashion. But such a distinct patter would surely have been noticed and drawn attention.
