>>17029937In the “theories” of general and special relativity, gravity is the result of the mass of objects bending space-time (the 4th dimension, described like a flat plane which all things in existence “sit” upon). These bends in space-time create what are essentially “funnels”, so objects are constantly moving towards each other because they’re always in these funnels (essentially always rolling towards each other). The mass of an object determines how large and powerful these bends/funnels are, and thus, the greater the mass of an object, the stronger it’s “pull”, as the more massive an object is, the more pressure it exerts on space-time, and thus bending it more extremely.
Of course, it’s a theory, not a fact. I, for one, lean more heavily towards a density and closed volume system as an explanation of gravity (after all, if the Earth was flat with a dome, there would be no such thing as a “vacuum”), where all “space” would be occupied by substances of various densities, and thus, always pushing one another.
