expand_less 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.
