The interaction may also be represented as reciprocal “potential pressures”. The object “pushes” against space and space “pushes” back.

This assumes that “space” is not absolutely empty.

Potential pressures lead to a definition of gravitational energy potential.

Two massive objects interact (as a binary interaction) through their gravitational potentials. A binary interaction must approximate to the Newton equation.
