Max noted: "And Yet, irregular galaxies are very common." The article says: “There is no theory that predicted these types of galaxies. The galaxy is a complete mystery, as everything about it is strange. How you actually go about forming one of these things is completely unknown.” The galaxy that is the focus of the article is the one that is least mysterious. The idea of dark matter is a hypothesis, since no one has yet directly detected such material, they only infer its existence. The galaxy in the article works the way we can model one with the information we have -- the verifiable information that we have; the classical model works better than the inferred dark matter model. Dark matter is a hypothetical substance that we speculate is there, because we cannot otherwise explain the mystery of how the other galaxies are observed to work. Thus astronomers tell us that they know that dark matter is there, because without it they can't explain most of their observations. It is sort of like observing a ball floating in the air and inferring that there is an unseen string holding it up.

There are many proofs of the existence of dark matter (or dark mass, rather). This discovery btw totally kills MOND, modified gravity theory, because it is not general but specific to these galaxies (both the one without any dark mass and the one that consists of it to more than 99%, both recently found).

One of the proofs of dark matter are the so called bullet clusters. They are dark matter free galaxy cluster pairs that have collided. All ordinary matter decelerated by interaction during the collision while the dark matter went on without taking notice, and left the cluster pair. Maybe something similar has happened to these sparse galaxies? Maybe these freaks were thrown off from galaxy mergers? The more galaxies are studied, the more freaks will be found. The “Backward” galaxy was an example. Out of thousands of known spiral galaxies, only one rotated the other way around relative to the direction of its spirals. But they’ve found more and an explanation for how a merger can cause this effect. Freaks are expected as more is observed, no reason to freak out.

These are found now because dim galaxies and dwarf galaxies are of great interest to astronomers now, in the quest for how the first galaxies were formed. It is really driven by the expectations on JWST. They want to tie in findings like this with whatever the JWST will discover in the first galaxies that ever formed, as it catches the first photons from “Let There Be Light”.

I agree with your summation.
They conclude that this galaxy has no dark matter simply because the stars are moving slower. It would appear to me, that it is proof, that “the combined mass of the galaxy itself holds the individual stars in check”. A Galaxy as large as the Milky Way with only 1/200 the mass would necessarily have stars moving much slower or they would be flying into deep space.
The article says;
“There is no theory that predicted these types of galaxies. The galaxy is a complete mystery, as everything about it is strange. How you actually go about forming one of these things is completely unknown.” And Yet, irregular galaxies are very common.
Ah, the uncertainty of science.
It was thought that matter (galaxies) cannot exist without dark matter. Well boys, it’s back to the drawing board…

Dark matter, dark energy, the 21st century label for ghosts , spirits, and hobgoblins….
Science from the flat earth society..
