Absolutely. A lot of my thesis could be considered classical mechanics (orbital dynamics, specifically). A very old problem that is still open is the question of whether the solar system is stable. (Newton worked on this question 300 years ago.) The state of the art can only reliably integrate orbits for the next few million years. After that, numerical limitations and chaos make it hard to predict exactly what the dynamics in the far future will be. All we can do is make statistical predictions (which we hope are unbiased). The best predictions are that there is a ~1% chance that two planets will collide before the Sun dies. Here's a nice article: http://www.scholarpedia.org/article/Stability_of_the_solar_s... |
