Of course under the gravity is due to spacetime curvature which is due to Mass model, Maybe field dampening isn’t a viable option.
In that case, we need to learn how to make spacetime curve without using huge amounts of mass. Learning to manipulate space time curvature like that might allow you to create gravity dampening or amplifying folds in spacetime. And that skill could come in useful in a number of ways, including creating planet sized worm holes in order to steal planets from other solar systems.
Of course you could use a wormhole to crash Venus into Mars, without disrupting gravity.
Mélange........Maybe that’s why Mars is red..................
