Recursive universe theory strikes again.
Comment on xkcd #2933: Elementary Physics Paths
Liz@midwest.social 1 month agoWhen 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.

They are both describing the same particles.

Water and ice are made up the same particles and molecules yet the mathematical to define the effect of force/pressure is very different - plastic deformation vs fluid dynamics as the example given above

I mean in the case of the comic, yeah the reason for the behavior actually is tied to pretty much the same principles, but the generalized statement you made isn’t, well, generalizable.
