- 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!
Didn't someone come up with an alternative model that said that, because galaxies vary in mass, time must also varies between galaxies; and said model was able to predict the effects of dark matter and dark energy?
Edit: it seems like a painfully obvious statement, which is why it confused me when I first read it. Like, no shit time is gonna vary between galaxies due to differences in mass.
That disputes dark energy accelerating the expansion of the universe. But AFAIK it doesn't explain dark matter.
Still, I find it very compelling. And I hope it might also solve the crisis in cosmology. At the very least it should get rid of the lambda in lambda CDM.
I've heard of something similar that is able to predict an effect of dark matter (the rotation curves), but AFAIK it couldn't match other observations (bullet clusters, etc.) correctly.
Do you have a link for the model you're talking about. I'm curious.
You're (probably) thinking of timescape cosmology theory!
