The total of the mass inside the area of concern.
It would constantly be "hammering around" in the hole. The Moon's effects
on the Earth are asymmetic, as are the Sun's. The net curvature due to the
mass of the Earth is zero in the hole. Not due to the rest of the
Universe. When you get away from point masses...
Just like areas of maxima and minima with light, or sound.
This is your error:
- the change in curvature *at some point* between two objects may be zero,
but the area between them is still a "low spot". Go far enough away, and
the curvature is such that the two (or more) masses look just like a single
