alt Hacker NewsWhat's so illogical about it? Galaxies are spinning as though there's matter that we don't see. Maybe there's matter that we don't see.

I have yet to see a model of galaxy rotation that doesn't use the shell theorem, which does not apply to disks. I've seen it in very advanced (over my head) math stuff on Wikipedia.
Im half convinced its gonna be a stupid mistake like that. Whoever finds the correct "advanced" math that allows the mistake to be brushed under the rug could get a Nobel prize.

Maybe there is, maybe there isn't. Maybe it's an un-acknowledged aspect of physics that we haven't properly discovered yet.
Assuming it's definitely matter, and operating on that basis for nearly 50 years, is not good science, period.
The fun question to ask is why almost all galaxies (no matter how they differ) spin as though a simple modification of gravity explains them. That dark matter is organising itself to produce the same outcome over many different circumstances!
