Dwarf galaxies suggest dark matter theory may be wrong
Thanks for the link, Shawn. The Cold vs Warm folk have been going at it
for years though. You might have seen a slightly earlier article pointing
out likely detection of cold dark matter particles already, still in the
early stages of the experiments.

It's an active field of research, as are the studies of galaxy formation
and first generation star formation (and supermassive black hole formation,
and a many other things about the early universe, it being a long way away
now, and hard to see).
Your article there is basically saying we can identify the existence of
dark matter, and identify galaxies forming in the early universe, but we
can't figure out /why/ galaxies look precisely like they do today if dark
matter particles are all of the "big and slow" variety.
No one can say yet what dark matter is, it being dark and all that, but
we can see it's effect on the universe at large.
