What makes gravity apply force to objects? Why does gravity not get pulled into the center of gravity itself, or scatter? I know that every physical body has some amount of gravity, that attracts other bodies. I also know that in order to make one physical body move, another physical body must apply force to it, so what is that physical body that gravity is made out of?
Also electric fields of magnets and atoms. What keeps the electrons from flying away from the nucleus? Is it same as gravity?
Is gravity our spacetime “sinking” into itself due to high amount of matter in one spot? Then what physical thing is the spacetime made out of to be affectable by matter?
I know its a lot of speculation and questions on my part, but i am fascinated by how physics does its thing.

I’ll take a crack.
The thing we call the electric field is a “field of influence”. It’s the English language expression of a mathematical concept that the closer you are to a an electric charge the more of an effect is has on you. Ditto with gravity.
They aren’t “made” or anything, they are the express a concept.
As our experiment get more and more sophisticated we (us, humans) found that you can’t have an electric field with a magnetic field. So we just call it the EM field. And when it’s really strong, sometimes, electrons and other particles will “appear” out of nowhere.
