I'm not sure how magnetism plays into all this. But it is interesting that these are
ultra diffuse galaxies. Maybe there is something wrong with how we extrapolate the rules
in flat space to the rules in very bent space, where everything gets so weird. It seems
(to me) that a regular galaxy would be more like a colloidal solution, with lots of
little clumps of bent space (heavy things like brown dwarves[†] and such). Such a
pock-marked, bristly, region of space must be more difficult to model than something
relatively well-behaved like an ultra diffuse galaxy. Right? In the vicinity of
"almost singularities" (very heavy objects), any measurement or calculation
error will have more of an impact on the result.
[†] I forgot to turn off the real-time spell checker on this new-to-me computer and, lo and behold,
"dwarves" is not the plural of "dwarf"! WTF?
https://grammarist.com/usage/dwarfs-dwarves/ tells me it's a neologism popularized by Tolkien. So,
by using it, I'm wearing my Dork on my sleeve.

with a whole lot of magnets/lots and lots and lots of gravity energy and
makes things go weird?
Or weirder?

The finding was highly significant because it showed that dark matter is
not always associated with traditional matter on a galactic scale. It also
ruled out several theories that said dark matter is not a substance but a
manifestation of the laws of gravity on a cosmic scale.
