> At the largest scales it is mostly purely gravitational to my knowledge (plus dark energy which is also modeled gravitationally). I think what OP might've been alluding to is the idea that phenomena like dark energy could have a more elegant explanation that is the result of emergent behavior at large scales. Just like magnetism was originally seen almost like magic, but it was later realized that it's simply an emergent property of the electric force i.e. electromagnetism.
