Dark matter is fucking bullshit.
Don't believe me? Ask yourself this then. What phenomena could we observe in the universe that would disprove dark matter? A galaxy that doesn't appear to have any extra dark matter in it maybe? Wrong, that actually (((proves))) dark matter.

How about just failing to detect dark matter particles at all? Wrong, again, that just (((proves))) dark matter is something else.

So why would physicists do this?
Simple. If something like MOND is correct (I'm not defending MOND, it has problems), then that means that the solution to this problem is someone needs to come up with a theory that explains our observations. It means that a brilliant physicist needs to devote years of study and experimentation to finding a theory that fits with our numbers.
If dark matter is correct, then we need a mind-bogglingly expensive detector to get the faintest whisper of dark matter particles.
Now ask yourself this. Of those 2 approaches, which one gets you a small army of interns, millions of dollars in grant money, and an expensive office near the gigantic detector? Which ones means toiling thanklessly in your small office working on theory after theory that doesn't quite satisfy the constraints of our observations?
Yeah, now you know why dark matter is bullshit.
