      When you section off a small part of the universe and try to model it, there’s little reason your model should look like a model for a completely different small part of the universe. Not unless they share fundamental characteristics that you’re trying to model. The math that describes permanent deformation looks nothing like fluid dynamics.

      Neither of them is trying to model the universe (that is the purview of cosmology). We are trying to model very particular phenomenon happening in the universe and there is no reason to expect them to modeled using the mathematical structure. The fact that they are is very fascinating.
