MOND may be a fringe but wholesale support of Dark Matter by mainstream physics has always seemed cargo culty to me. Over a hundred years and we still don't have a good understanding of dark matter.
A red flag to me is how there doesn't seem to be large amounts of dark matter in areas closest to us where we can see best. It's all this far off enigma. And at least originally the theory existed to explain why the laws of gravitation didn't line up with visual evidence.
To me "half the matter is invisible" is just as outlandish as "maybe our math is wrong about gravitation". I don't think enough of the community questions the dark matter theory.
Well, maybe the thing is you just don't know anything about it. Current dark matter concepts are 40 years old, not over a hundred (again, Wikipedia is not a substitute for an education). And we have detected indeed a very common kind of actual dark matter, predicted 26 years before you could "see" it simply because it explained the data, we call it neutrinos. The universe is brimming with cold neutrinos btw.
Everything seems outlandish from a prejudiced superficial POV.
Probably, but then HN commenters could reduce this tendency of stating that whole scientific disciplines don't know what they're doing/are full of deluded morons. Particularly when it comes to physics. At some point you have to mention the other possibility.
Who gave you the idea that it's over a hundred years old? The solid results are from the 70's, while a hundred years ago it was still an open question if galaxies really existed...
Not sure what you mean with there not being any dark matter (DM) in our neighbourhood, the DM content of the Large Magellantic Cloud is estimated to outweigh the visual matter by a factor of 4, and the LMC is right up in our face.
