You can describe things in two ways: 1) Decompose into smaller components and put back together 2) Look at it's structure It's the diference between describing a cardboard box and a cube (platonic solid). To describe the first, I have to describe what is cardboard, what is cellulose, what is a cell, what is matter, ... all the way down, and then I hit a wall. To describe the second, I just need topology. This definition of space is that space "just is", resembles a network, and that the "stuff" in it is just how we perceive particular local structures. The network is only a geometrical analogy, there's no "space" between the nodes because the nodes don't represent anything concrete. You can describe the same network algebraically, but then you're left with no pictures to illustrate the article.
