This question already has an answer here:

An electromagnetic field can be diluted in a volume by using a dielectric. The polarization of the dielectric material results in the field decreasing in magnitude.

Can a gravitational field be similarly "diluted"?

To quote the Wikipedia article on gravitational shielding, "gravitational shielding is considered to be a violation of the equivalence principle and therefore inconsistent with both Newtonian theory and general relativity." You can also think of this as being due to the fact that mass only comes in one flavor, positive.
