can you think of gravity as space itself shrinking directionally? and the time dilation effect could be due to the velocity of an object on the surface of the Earth through this shrinking space. Also the acceleration of a falling object due to gravity would merely be the object losing its upward momentum from when it was held in place? This would mean gravity(g-force) is merely inertia. The part that doesn't make sense in the this hypothesis is that the shrinking would need to be accelerating as an object that experiences g-force must be resisting acceleration.
