How the Edge of Our Galaxy Defies Known Physics

I'm not gonna pretend to know the maths behind the whole theory of Dark Matter, but just in a theoretical sense it's always seemed like a red herring to me. As in, there's some obvious answer just staring us in the face and we're not paying attention to it because the whole community of physicists are obsessed with this one approach. The idea that our concept of gravity is flawed in some way holds ground imo, but I'd wager that the solution to this problem is not as complex as we think it is; it's basically the implementation of occam's razor.


Like how in the early renaissance, mathematicians could create models for a geocentric solar system easily, and predict the positions of planets accurately (sort of) but as it turns out, the geocentric model offered a much simpler and cleaner model than the already established and continually improved one from earlier astronomers.
