Dark matter might not even exist, all we know is that gravity-based predictions break down after a certain point. Dark matter is the just the most popular proposed solution where you essentially just add extra undetectable mass until it works. The distant second is Modified Newtonian Dynamics (MOND) or some variation of it, which is where you try to tweak the theories to fit observations instead. It has the same problem as dark matter where we keep coming up with better experiments which always fail to find anything.
There’s a similar problem at the opposite end of the scale spectrum too; quantum mechanics doesn’t play nice with our current understanding of gravity leading to the search for the “theory of everything”. This is why I personally lean towards the idea that it’s our theories that are wrong and not an undetectable mass, but this isn’t my field so my opinion isn’t worth much (especially since a majority actually working in the field lean towards dark matter as far as I can tell).
So in other words, the big equation of gravity gives us a formula on one side, and the solution + x on the other, and we have to solve for x (dark matter) but we don’t know how to do it yet
I think I was listening to the unexplainable podcast and they were suggesting that gravity may work differently at smaller scale. Like the nooks and crannies may have different dimensional properties at the atomic or subatomic level. I dunno if I explained that right but it definitely got me curious. Like, we observe gravity as it effects large quantities of mass so, like temperature, it’s really just an average of all the different factors at play.
