'Cosmic radio' detector could discover dark matter within 15 years

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?

Well you have things like the bullet cluster that can't be explained by math being wrong.

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.

99% of the evidence points to dark matter being a real thing. And yes, many many phds have thought of the "what if we're just completely wrong" aspect. It's not interesting

So yes. It is a missing term that balances our models of physics against observations. The implications of that term and hypothesis as to its physical reality are what we are trying to figure out right?

Of course they can. The whole reason you think they can't is just more math.

If you mean particle dark matter, that's an exaggeration:

There are pretty math pathways to dark matter, though, and they tend to be more compelling reasons to believe there is something that fits the notion of a particle that we can't detect (or is very difficult to detect). Specifically, bariogenesis calculations, given the current standard model, actually require dark matter--it's the label we've arrived at--as a result. Observations led to the hypothesis, calculations led to more evidence.
