Notice in that article that there's no mention of plasma. No mention of electro- anything. No mention of magnetism. It’s just gravity, gravity, gravity and gas, gas, gas, even though they do acknowledge in the paper the existence of “ionized gas”, i.e., PLASMA.UC IRVINE ASTRONOMERS’ SIMULATIONS SUPPORT DARK MATTER THEORY
Irvine, Calif., April 29, 2024 — Computer simulations by astronomers support the idea that dark matter – matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe – exists, according to the researchers, who include those at the University of California, Irvine.

The test involved running computer simulations with both types of matter – normal and dark – to explain the presence of intriguing features measured in real galaxies. The team reported their results in Monthly Notices of the Royal Astronomy Society.
The features in galaxies the team found “are expected to appear in a universe with dark matter but would be difficult to explain in a universe without it,” said Mercado. “We show that such features appear in observations of many real galaxies. If we take these data at face value, this reaffirms the position of the dark matter model as the one that best describes the universe we live in.”
These features Mercado noted describe patterns in the motions of stars and gas in galaxies that seem to only be possible in a universe with dark matter.
Here is their paper (with EIGHT authors) … https://academic.oup.com/mnras/article/ ... ogin=false. It too doesn't mention plasma or electromagnetism. And I bet the simulation tool they used, Fire-2, did NOT include the various effects of electromagnetism on plasmas that were discovered and posited by plasma cosmologists as important in shaping the universe.
Indeed, while the tool's website (https://fire.northwestern.edu) claims it models "magnetic fields and higher-order plasma physics”, except for that one mention of plasma and magnetism, nowhere else on their website are those phenomena mentioned. It’s all gas, gas, gas … gravity, gravity, gravity. So I seriously doubt their studies modeled Birkeland currents, double layers, plasmoids and a host of other important phenomena. And there-in lies the problem with their results.
If they won’t acknowledge that plasma behaves differently in the presence of electric currents and magnetic fields, which we know abound out there ... which they, in fact, refused to admit were ubiquitous out there until quite recently, then there's no possibility their study is anything more than garbage in and garbage out at taxpayer’s expense. But astrophysicists all expect to live high on the hog these days, thanks to taxpayers, so they are not about to give that up. They’ll lie to themselves and the public if that’s what it takes.
