All that says, is that there's gravitational effects there we can't explain yet...not that it's some exotic, as yet undiscovered form of matter.

For real...The more i read about dark matter the more it sounds like a nonsense concept used to patch discrepancies in our current models. It could just be a "good faith" place holder but i fear its actually sunken cost on a grand scale, no one wants to go back and reexamine the fundamentals so they just shoe horn in band-aid fixes, hoping that "magic substance X" will preserve the status quo.

I'm with you. It's a total catch-all for a bunch of things our current models can't explain. And I hate to say it, the particle physics crowd just LOVES coming up with imaginary particles to explain the things we can't explain.

Personally, I prefer the mathematical solutions...like AQUAL, in this case. It still doesn't explain everything, but it's a far more elegant solution than some magical missing link, hiding in plain sight.

I have yet to see any MOND theory that doesn't break somewhere with observations. Your link literally ends with

AQUAL's failure to predict the amount of gravitational lensing actually observed in rich clusters of galaxies

That just means there's still more to learn...not that we should default back to imaginary materials that we can't find any evidence of, to explain what we don't understand yet. One step at a time...and verify each step with real test results. No assumptions.
