- Are dark matter models unsuited to explain observations? [the "dark matter models" and "to explain observations" parts are poorly edited onto the image, overlaying the original text]
- In my view, they are unsuited.
- Why?
- That's my opinion, don't ask me why.

Dark matter is the mainstream among physicists, but internet commentators keep saying it can't be right because it "feels off".
Of course, skepticism is good for science! You just need to justify it more than saying the mainstream "feels off".
For people who prefer alternative explanations over dark matter for non-vibe-based reasons, I would love to hear your thoughts! Leave a comment!
MOND isn't even a great way to explain rotation curves. It's pretty easy to make a pretty close model for the majority of galaxies, but there are a lot of weird outliers where it's pretty easy to say they just have more or less dark matter than usual, but MOND has a really hard time explaining them without making it so that physics works differently in different galaxies.
I must admit I don't know that much about MOND being tested. But yeah, from a Lambda CDM point of view it is unsurprising that MOND would not work well for every galaxy.
