What is the source for gravity, or what causes it in things? I understand that way massive the object is, the force will be great (and depends on length between a second object too), then, the object creates it? How?

TLDR: We aren’t entirely sure yet

Gravity is one of the fundamental forces of nature, but unlike the other forces like electromagnetism, the strong force, and the weak force, Gravity doesn’t have an opposite (that we are aware of) that cancels it out. It is also the weakest of the forces by far but also seems to accumulate without limit.

What we perceive as Gravity is a warping of the fabric of spacetime and appears to be directly linked to mass. Objects do not fall towards a massive object because there is some kind of particle or force pulling on it, but rather because spacetime itself has become warped so objects fall towards each other like a ball rolling down a hill.

One current theory is that mass, and by extension gravity, is imparted onto things by the presence of sub atomic particles. This might be the Higgs Boson, or a theoretical particle called a Graviton.

It wouldn’t be gravitons flying out and pulling on an object that causes gravity, but rather the presence of gravitons warps or bends space
