Visit for an updated, higher-res version of this animation. A visual experiment to see what happens when an array of physically proximate particles begin expanding: Individual particles expand into one another and eventually form stable clusters, bound by the outward pressure of their expansion. Those stable clusters would continue to expand into one another to form larger superstructures of wildly varying size and complexity. For the next 13.7 billion years, every physical object in our universe would be composed of snowballing clusters and superstructures of expanding particles, that would continue expanding right along with the rest of the rapidly inflating universe. In fact, if everything were made up of particles expanding at the same rate, then from within the universe it might be nearly impossible to tell that the expansion was happening at all, but expansion at a particle level would be driving the expansion at a cosmic level. Now remember that we are a part of the framework we observe, so every person would be made up of those same expanding particles, and all we would directly observe is the appearance of large masses moving towards one another. At the tiniest scales, this effect might look a great deal like the strong nuclear force. At larger orders of magnitude, it would look a lot like gravity.
