Honest question. If the concept of dark matter flows from our current understanding of gravity, and gravity is so admittedly poorly understood, how confident are we that dark matter is "a thing"? I know an intuitive sensibility is not the best foundation for an understanding of The Universe, but every time I read about dark matter, I get a very "Aether"-ish vibe. I just imagine comments section in the 2070 version of HN getting a good natured laugh about dark matter.
