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.
