Gravity fields are just potentials, as gravity requires at least two bodies, right?
If the universe only contained one body of irrelevant mass, without anything else to interact with it would just sit there. Further there would be no time, as there would be no change.
If Earth’s mass were to double, all gravitational relations, including potentials, would also increased but it’s not exactly double as the equation should also account for the other body or bodies masses.
I’m not a scientist, I’m just smoking weed on a sunday. I’m hoping some actual smart people can explain this like I’m high.

I think the simple Newtonian version is: Break down each gravitational relation (A and B pull on each other) in it’s components: A pulls on B, and B pulls on A. If you double the mass of A, this has two effects:
A pulls on B twice as much
B pulls on A the same, but needs twice as much force to achieve the same acceleration (a = F / m)
