Hi Thomas welcome to Icenspace.
I think it would be useful if you post the animation that is giving you the impression that you outline. To answer your questions we really need to see what you are basing your questions upon...
It sounds like you are talking about the "space time grid" ...
The Moon does orbit the Earth in what I suppose one could call multiple orbits and the Earth and the Moon (system) orbits the Sun...and the Solar System orbits the central region of the Milky Way...past that the Milky Way is part of what is referred to as the Local Group of galaxy but I don't think the paths of galaxycies within the local group could be seen as orbital.
If it is indeed the "Space Time Grid" you contemplate I suppose the best way to explain it is to understand space time is a term used by the scientific model known as "General Relativity" and it is a co ordinant system that enables modling of how masses relate to each other which we call gravity. You may come across illustrations of a grid supposedly representing space time that is distorted but the grid is finally a geometric construct derived from the principles contained in the scientific model we call "General Relativity". As I said the model is a co ordinant system and the best I can put it is the distortions in the grid somewhat represent gravity or paths objects will follow when moving through space.
General Relativity does not treat gravity as a force which is hard to comprehend but perhaps one should remember that GR is a scientific model and simply via its approach has no need to regard gravity as a force.
Further I don't think GR sees gravity as either pushing or pulling..a result of not needing to treat gravity as a force.
I suppose the main message is that to understand GR one really needs to do a course and even then perhaps one will find it still just out of reach of full understanding.. As a layman one has little hope of understanding how professionals view it.
