- The latest issue of S&T mentions some recent work done using chaos
- theory and large computers to see whether the solar system is stable.
- Their finding (I forget who it was now) was that millimeter
- perturbations in the orbits of the planets do cause chaotic changes in
- the long run. The good news (for people who don't like chaotic
- orbits) is that the amount of time it takes for something ``really
- bad'' to become probable is on the order of a trillion years [i.e.,
- longer than the solar system will exist in its present form anyway].
- ``Really bad'' is for a planet to be ejected, a collission, etc.
