This is an interesting question.
According to Einstein and relativity, which transformed our understanding of the universe, it is all to do with spacetime itself.
Gravity is a reflection of the shape of space, so for instance a body that has a high mass literally affects the shape of space around it.
The classic demonstration in two dimensions is to imagine a rubber sheet, with a big heavy ballbearing placed in the middle. This depresses the rubber (representing space) and then if you roll a small ballbearing around the outside it will fall into the big one, representing gravitational pull.
