Take a coin, lift it above the table and release it, it falls or gets into motion; gravity in space, or a gravitation field, is nothing else than the motion of the coin that you see! Hence the word gravimotion by the way.
Now here is a detailed model of the radial-activity (gravitation field) surrounding a material object as introduced in §4.1; and whether the object be a proton, a coin, a meteorite, the moon, Earth or Sun, the model is the same, the scale only changes.
The motion-occurrences that form the radial-activity are all inclined on average toward a center on the move itself.
The closer the MOs to that average center the more thrust they have (the thinner their representation); also the closer to that average center the tighter or the better the tuning of their inclination; and these 2 geometrical characteristics (thrust and inclination) parallel physics force of gravity, which increases while getting closer to the center.
The farther the MOs are from the average center the less thrust they have and the rarer their population.
Some pure-activity motion quanta are still coexisting with the radial-activity motion-occurrences, as in this particular case the local MQ’s have not been all converted into MO’s.
Furthermore in gravimotion the mass of the material object at the center is not only not represented, it also doesn’t exist!
As such or because our human concepts of mass and gravitational field make one (in gravimotion), the motion-occurrences of the model represent both an object's matter in the center and its surrounding gravitational field.

A short recapitulation:

1. Motion quanta and motion-occurrences are constantly wiggling around, no matter their concerted activity. In the case of radial activity the MOs individual thrusts are on average inclined toward a common center; the closer they are from the center the more intense their wiggling inclination and thrust.
2. Radial-activity, which is considered to be static in physics' concept of gravitation field, is not static in gravimotion; the MOs inclination constant wiggling that is their radial characteristic coincides in gravimotion to our human concept of time.
   An analogy can be found in our human aging which is a motion occuring in time only (gravimotion's motion-inclination) as opposed to a motion occuring in space.

Physics static gravitational field is given a tangible that is physical, furthermore energetic yet live constitution.
The Nature of a gravitational field is motion occuring as radial-activity.
A gravitational field is a live construct out of pure-activity motion-quanta (space §3.1) and is not a byproduct of mass.
