That's so classical to measure with my theory.
Mass is really great alternative unit to Measure gravity and measure altitude of satellite. But it can't explain what is gravity and why gravity exists. It says that gravity makes two particles attract. But why?
And this attraction is just one effect of gravity but not what gravity is.
Where as volume says that space doesn't want foreign object to occupy it's place and hence space tries to reclaim it's place through a force which is called gravity. And when the object is removed, the sudden movement by space trying to occupy the volume will cause ripples in space which is called ripples of gravity.
Mass also cannot explain gravitational ripples in space coz mass only considers object itself. So, how does gravity exist in the form of ripples when there is no mass at that place?
Whereas the view from volume can explain that ripples in space.
