Is the strenght of a gravity Field a function of space pressure on a mass structure in the Universe?

Answer 1

That is an interesting way of looking at gravity. Einstein had a different idea in which space was distorted making objects accelerate towards a mass.

Answer 2

No. Pressure is a force acting over an area. Classically, gravity is independent of area, it is only dependent on mass and distance .
Form a relativity point of view gravity is a function of the local curvature of space.

Answer 3

There is no push gravitation. Gravitation is strictly attractive, hence the necessity for a spin-2 tensor boson propagator if quantized.

The Weyl tensor is gravitation without mass. The vacuum is homogeneous and isotropic, hence respective conservations of linear and angular momenta through Noether's theorem. The vacuum is structureless (but filled by Heisenberg Uncertainty - Casimir effect, Lamb shift, Rabi vacuum oscillations, electron anomalous g-factor...).

Answer 4

Interesting idea, but I don't think so. So-called 'dark energy' fills something like 73% of the universe and seems to be counteracting gravitational energy. In other words, 73% of space is working to decrease gravity.

Answer 5

No the gravity is what puts the vacuum on space as every thing is pulled toward the sun,planets , and black holes.
