It's durable- at least in terms of our ability- ours smarts to measure it.

True in the short term.

Chaos in the solar system. Yeah, I suppose it's quite likely to be there, but making an observation of such a thing seems tricky. The place you'd expect to see it is in a Poincare' slice of planetary orbital trajectories. To build up enough data to confirm such a thing (via observation) would take many thousands of years. Probably easier to find it in turbulence or molecules or someplace where things are movin a little faster. I really wonder how chaos and perturbation theory can go together in astrophysics. Say you had a nice chaotic attractor going and things get perturbed by an asteroid - what then. Either it continues the same pattern, morphs, or goes non-chaotic. Feigenbaum's constant or something similar may have some application for that. |
