If dark matter is only affected (effected?) by gravity, would it tend to collect in massive bodies like planets, stars and black holes? Would that mean the gravitational constant could change locally depending on the amount of locally available dark matter? Could this have something to do with the shrinking mass of the standard kilogram?
