At the most general level at neme is a bounded network. Bounded means that it is possible to say that something is inside or outside the boundary. Each neme - bounded network - evolves. The shape of a neme is not a sphere. It is more like an ameoba. Under some conditions the shape of the neme gets smaller. Under different conditions it gets a larger. Sometimes there is a bump in the boundary. Under certain conditions the boundary of the neme cracks. Sometimes the cracks open far enough to fracture the boundary. It is like an small earthquake along a fault or a large earthquake that opens the ground. (The ground is the boundary of the earth. In that sense the earth itself is a neme.
