RE: Dragonfly 44, a galaxy of the dark side made of dark matter
Folding space and Alcubierre drive are currently only speculative although connected to relativity. Adding on top of that that the physics behind is not too close to what I am doing... I am afraid I will not write on that. Apologies!
Also, when you say "failed Milky Way", could that possibly mean that that is where all dark matter comes from; failed galaxies from an earlier tightly packed universe?
It is a failed Milky Way in the sense that the Dragonfly-44 galaxy could have become a galaxy such as the Milky Way, but for some reason that we do not know (yet?), the stars have not been formed. As a results, the galaxy mostly contains dark matter and nothing else. That's the only thing we can say.
Concerning dark matter, first we do not know what it is. It is only an hypothesis that works well to explain everything we observe. We still need to discover it to validate this hypothesis.
It is however not related to black holes that are different objects (with different properties) and if it exists and if our explanation for the universe history, it was already there everywhere when galaxies started to form.
I hope this helps!
