There's actually an embarrassingly large number of theories for what makes up dark matter. I doubt most people have ever even heard of the form that was ruled out in this article. There's not just a ton of theories, a great number of them are falsibiable with experiments we can plausibly perform.
And yes, quantum gravity is also something we don't understand. But the domain where we are missing that understanding doesn't overlap with the dark matter "problem".
- akvadrako 5y agoHaving a large number of theories is embarrassing! That means you have no idea. Gravity and QM are so great because they are clear winners – they are not easy to modify a little bit and nothing approaches them in terms of practical power. Falsifiability comes from having specific predictions, which means one theory that's an island, not a bunch of approximations.
