I am trying to understand how curvature in spacetime as depicted in many diagrams can cause a force that behaves like gravity. The curvature lines depicted in in this diagram to not follow the path the object would take under the influence of gravity. Just with your eyes, follow one of the curvature lines... An object would not follow that path under the force of gravity. And the text books always just say that objects only follow the curvature path.. nothing more.. But like I said, if you follow those curvature lines, it does not behave like a force. I could use some help understanding why these curvature lines would cause an object to follow the path that mimics an object under the influence of gravity. OR are these diagrams accurately portraying how warped space would look from 3 dimensions???

To understand the idea, you need to understand the main concepts of how general relativity deals with gravity: matter/energy cause spacetime to become curved, and particles in freefall (no nongravitational forces acting on them) follow geodesic paths in curved spacetime, which for slowerthanlight particles means paths that maximize the proper time relative to other nearby paths. If you haven't come across these ideas before, I recommend reading a good nonmathematical introduction to the concepts of general relativity written for a layman audience, like General Relativity from A to B.

Complexity of dimension is not known Influence of gravity is not uniquely defined , maybe gravity is a sideeffect
