When a Galaxy can no longer expand by building more Trinary Engines, it will stop production and start to morph into a different type of Galaxy, currently, these are classified as either Irregular or Elliptical, I will only refer to them as Older Galaxies or Mature Galaxies, a progression of this can be seen in: Illustration 4.10: Hubble's Galaxy Classification, once you understand the pattern, it is clear that this is just a natural part of the Evolution of a Galaxy.
I see no reason at this point in time to change any of Hubble's Science, it is all based on Newton's Math, so its something we can all agree on; so this chapter needs a lot of work, I would like to detail how this shape comes to be, and show more images of this type of Galaxy, and where they can be found.
