Let's imagine that an object was coasting through space following the path of the curved space time. Now curved space time actually has many paths in different directions, and not just one as is displayed in the above simplified drawing. We have ‘momentum' in our momentum field and because we have direction we assume that polarization is important (we are moving in a certain direction because our momentum field is ‘polarized' and this then has the result of polarizing the surrounding space field (we assume that the space is just the result of one more metamorphosis of that chameleon known as energy, appearing at one time as a tossed salad of matter mass, at another time as an electromagnetic wave flying through the space field, and then yet another time as a three dimensional spatial field...this type of thinking is required if we are to make any sense out of something as weird and incomprehensible as ‘conserved momentum').
This space field is best thought of as being a type of magnetostatic field where the energy exists in a state of psuedo-rest until the entropy of the system is disturbed by some wandering matter surrounded by a momentum field. The only way to restore the entropy of the system is push the matter out of the way. In this way things would move through space like toothpaste being squeezed out of a tube.
We can then imagine what would happen if the momentum field strength increased. Since we assume an equivalence between energy and space, therefore more energy in the momentum field means more space being invaded by the momentum field of that object, and therefore more of the surrounding field would be involved in restoring the entropy of that disturbed system, resulting in more pushing and squeezing, which then produces the result that greater momentum equals greater velocity (more force is involved). If an object is moving through a strengthening gravitational field it experiences ever increasing acceleration as the field strength increases, even though its momentum remains constant. The field is denser. Once again there is more and more of that pushing and squeezing.
The purpose of this simple though experiment is to suggest that the ‘g force' is not something that comes out from a point somewhere in the center of the earth and then pulls and tugs on things. We assume that more momentum means more ability to polarize the surrounding field, and therefore it is less likely that the surrounding field will polarize us, and therefore push us down when we were actually planning to move horizontally.
As for that ‘g force' of motion that you feel when sitting on a chair, that is just the constant squeezing of the energy field. It is an anthropocentric projection to assume that a ‘g force' is something that you ‘feel'. You only feel that g-force because you are not moving out of the way and you are not moving out of the way because quantum forces in your atoms and the earth's atoms are all pushing back at the energy field, causing you to ‘feel g-forces'.
You also feel those G-forces when you are building up momentum as you accelerate, and the reason for that is that you are encountering the force of ‘inertia'. According to Newton that ‘inertia' was a property of masses of matter. We will think of that ‘inertia' as being a property of the energy field. You are disturbing the entropy of that field and so that field is going to push back on you, and you will feel that pushing as you get pushed back into the seat of an accelerating automobile. The only solution is to gain momentum and the field energy required to polarize the surrounding energy field, so that the field will push you in the equal and same direction instead of pushing back on you in the equal and opposite direction.
