Dwarf galaxies suggest dark matter theory may be wrong

And...? What does this have to do with GURPS?

With GURPS qua GURPS absolutely nothing. With a recent discussion in
this forum a great deal.

The whole theory sounded a bit dingy to begin with.

Shawn, did you actually read that article, or just look at the title?
It's talking about adjusting theories to replace "cold dark matter" with
"warm dark matter," not eliminating dark matter entirely.

Like I said in one of my replies to your earlier flame, it's not that
surprising to have people fiddling around with many variant theories in
the early stages of trying to understand some phenomenon.

Did you read the whole thing? It basically says "wrong" in some
details, not "wrong there is no dark matter".

Gather data, make hypothesis, test predictions, repeat until all
predictions agree with the data, within limits of error.

When the error limits get smaller, start again if necessary.

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.

http://www.bbc.co.uk/news/science-environment-14811580

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.
