- 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!
This is a very fair take, but I'd say dark matter is harder to falsify, but not totally unfalsifiable.
You can't see it, true. But what makes sight so special? We can't smell stars either. You just need to sense dark matter in some other way. Namely gravity! We have seen the way visible matter orbit, and that points to dark matter. We have seen gravitational lensing due to dark matter. Hopefully soon we'll observe gravitational waves well enough to sense dark matter around the regions the waves are being emitted from.
Most individual dark matter models are falsifiable (and many have already been falsified) through non-gravitational means too. People have been building all sorts of detectors. The problem with this is that detectors are expensive and there are always more models beyond any detector's reaches.
