I think we need to separate our imagination from what is happening in the outer space because our mental capacity is limited to the reality on earth. If we imagine coordinate planes or nodes networking to form hypergraphs in space that supposedly curve in under the influence of gravity, it doesn’t mean they’re there. We can use them for reference or explanation purposes, but in my opinion, what curves is the direction of the motion of celestial bodies after they engage in a mutually symmetric motions caused by gravitational attraction(mainly due to the only available effects of force-their inertial mass and the galactic pull). These two effects are multiple times magnified due to the absence of friction and abundance of degree of freedom in the vacuum of space. Remember gravity, angular momentum, and acceleration inherently happen in a vacuum of space that enables the flawless (frictionless) orbital motion of massive objects. A minute presence of friction would prevent the Big Bang from happening, and we wouldn’t have our universe.
