From New Atlas:
Some of the strongest evidence for dark matter to date has been discovered – and ironically, that's thanks to its absence. In a pair of studies published this week, astronomers have shed new light on dark matter through close observation of a galaxy previously found to have very little of the stuff, while the same team found a new example of a similar oddball galaxy.
It's generally believed that galaxies are held together through the gravitational influence of clumps of dark matter, so to find a galaxy with little to no dark matter was a surprise. And while it might sound like a strike against the theory, it actually ends up supporting it.

Yeah, here we go again...
..."It has none...which is PROOF the thing that doesn't exist DOES exist! Just like My ass DOESN'T have whip cream all over it, so whip cream on asses exists! PROOF!
God exists BECAUSE we have no proof he exists! PROOF!"
More pseudo-scientific garbage...
AAAAACCCC!

See the thread above. Not only do these fail to contradict MOND, a MOND prediction for this new "no dark matter" galaxy was published beforehand.
This dark matter propaganda is really stretching credulity at this point. I am beginning to doubt that they are being intellectually honest, and thinking instead there is some scam going on.

Yup: QI too.
The scam is that they get loads of funding for DM, just like how they (used to?) get loads of funding for string theory.
Follow the money, find the reason for crap.

Why can't they get loads of funding for MOND/QI? Just because dark matter is so vague?

Dark matter is 'established' science while QI and MOND are 'pseudo' science.....so say we all.....all except those that realise that dark matter was JUST created out of thin air to save General Relativity.
Instead of realising that GR has faults, the DM magicians waved their hands around and said Abra-cadaver enough to get noticed.
QI just got some DARPA funding, though. Good news for REAL science.

I dunno man, reading what people say not just here and elsewhere it looks like blindly repeating mantras. I couldn't even get khallow to recognize the publication date of a prediction is before the publication date of the rotation curve data for the second "missing dark matter" galaxy. All it requires is looking at the dates on two documents.
He has apparently been rendered incapable of making a simple comparison between two published dates, that is some pretty strong mental gymnastics. Think about it.
Then he "just doesn't buy it" that the equations for MOND published in 1983 are the same ones used today. He provides no source or reason for this, just intuits it I guess. It is like their minds reject actual science making consistently accurate predictions without post-hoc fiddling as impossible.
So I suspect shilling/trolling.

People in this thread seem very opinionated but totally ignorant of the topic (eg, Mr Khallow above). They just string together a bunch of blatantly false things about MOND, and then conclude therefore dark matter is a great idea. Is that normal? Or are they trolling?

Explain why MOND works, then we'll have something to go on. In the mean time, we already know that there is dark matter, but what we know of isn't enough at present to explain the observed discrepancies. Finding more dark matter is not that big a stretch. A theory of gravity that can't be observed anywhere near Earth should already be tripping alarms for you.

MOND is not the droid you are looking for...QI is.

"Gravity," per se, does not exist. It's an artifact of the distortion of spacetime by mass.
How does that old saw go again? Spacetime tells matter how to move; matter tells spacetime how to curve.

An observable artifact. That makes it just as real as anything else you can observe.
