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?

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?

Answer 1

We don’t exactly know why, but the bigger the mass, and the shorter the distance, the stronger the force, as given by gravitational equations.
