Summary:
Dwarf galaxies that orbit the Milky Way and the Andromeda galaxies defy the accepted model of galaxy formation, and recent attempts to wedge them into the model are flawed, reports an international team of astrophysicists. A new study pokes holes in the current understanding of galaxy formation and questions the accepted model of the origin and evolution of the universe.

According to Quantum FFF theory ( Function Follows Form) there are two kinds of dwarf galaxies. A Globular clusters formed around single GABHs ( galaxy anchor black holes) and
B irregular dwarfs like Zwicky, formed between two or even more GABHs.
GABHs are the anchors of spiral galaxies and are not supposed to rotate around the galaxy.
Conclusion: Dwarf galaxies also do not rotate around the galaxy, but could slowly be attracted to the main galaxy and become a merger.

Red Nuggets are supposed to form around single black holes, just like globular clusters.
