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?

We don’t know yet. But we do know little bits of the world -subatomic particles- tell everything bigger than them how they work, from radiation to electricity. We think there might be bits called gravitons that tell their bigger parts how gravity works, but we haven’t seen one yet.
