I’ve always felt like (as neither a mathematician nor a physicist) that “dark matter” is simply just something that suddenly makes a math problem work to model the universe-—and that in reality, that math problem just doesn’t work. Is my theory even _possible_ here, or am I missing something. Really fundamental?

We do have a pretty substansive evidence that dark matter exists: from the cosmic background radiation, gravitational lensing, galaxy formation simulations, galaxy rotation curves, etc. Why is it so hard for people to believe that there are some particles that are not interacting with electromagnetism that we haven't detected directly yet? It's not even a precedent, the neutrino is just like that. I guess the name "d…
Not trying to be a mindless skeptic but your “why is it so hard” question seems bizarre to me. It seems quite understandable that it’s hard for people to believe there’s a particle responsible for a significant percentage of all matter in the universe that we have no direct evidence of and the only reason it’s believed to exist at all is because a lot of otherwise well-understood equations and observations require it…
But we are not very well educated so yeah, they will doubt it for no good reason other than "it doesn't feel right"

Dark matter is a proposition put forward to explain observations. It’s not a result of pretty math, it’s the result of a lot of different observations which don’t align with the current math unless you stick something like dark matter into it.

I agree with you. "Dark Matter" (and "Dark Energy") are colorful (colorless?) names that I think helped these theories diffuse into the popular consciousness at a time when popular interest in science was at a high-water mark (remember when "chaos theory" was fashionable?). As I mentioned in another comment recently (it feels like a "Dark Matter" or "Dark Energy" headline trends on HN almost every day), this coded th…
Had we named it "invisible matter", perhaps not as much controversy would surround it.

#37Am I wrong to assume that science that is harder to prove will have less impact on human wellbeing? Electricity is easy to run experiments on and prove, meaning humans can manipulate it for our benefits easy. However, the Higgs Boson was extremely difficult to prove and I see no way that it could ever benefit humanity's wellbeing. Now how could humans improve our wellbeing by manipulating dark matter?

#38> FWIU this Superfluid Quantum Gravity rejects dark matter and/or negative mass in favor of supervaucuous supervacuum, but I don't think it attempts to predict other phases and interactions like Dark fluid theory?
From https://news.ycombinator.com/item?id=42371946 :
> Dark fluid: https://en.wikipedia.org/wiki/Dark_fluid :
>> Dark fluid goes beyond dark matter and dark energy in that it predicts a continuous range of attractive and repulsive qualities under various matter density cases. Indeed, special cases of various other gravitational theories are reproduced by dark fluid, e.g. inflation, quintessence, k-essence, f(R), Generalized Einstein-Aether f(K), MOND, TeVeS, BSTV, etc. Dark fluid theory also suggests new models, such as a certain f(K+R) model that suggests interesting corrections to MOND that depend on redshift and density

#39A headline using the word "could" implies "but probably won't". Report on things when they happen. Don't speculate.
