A massive object interacts with surrounding space. This “spatial interaction” which extends into surrounding space is a “field interaction”. 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.

Can space be "pressurized"?

The object “pushes” against space and space “pushes” back.

Can you quote some evidence of this?

Center of massive object?  If the object not black hole has finite density,  then .the force at the center is 0.
