Another way to look at gravity:
Imagine space is a liquid. Imagine atomic & sub-atomic particles as drain holes, in which the liquid of infinite space is constantly flowing into forever. The constant draining action creates micro-vortices, but in the 4th dimension (spherical). The higher number of "drain holes" in a given area = higher gravity.
A comparison of this effect to something you're already familiar with: let's say you're at the bottom of a pool and the drain opens up. You're now drawn to the drain. If you get close enough to the drain, you're stuck to it. Hence, gravity. Astonishingly simple, when viewed in this way.
