An interesting aside about gravity

[knocker]

 

In the past, when discussing the role of chaos in climate models, I’ve been known to argue that the complexity of multi-body dynamical systems means that we could probably not run a model of the formation of our Solar System that would actually produce a result entirely consistent with what we see today. That doesn’t mean, however, that we can’t use such models to understand how our Solar System formed and evolved. Similarly, that climate models are inherently chaotic does not mean that we cannot use them to understand how our climate might respond to changes in anthropogenic forcings. The response I would typically get is that gravity is verified/validated (or whatever other term the person chooses to use) but climate science is not (ignoring that much of the underlying physics is about as well understood as gravity).
