Gary, it has been pointed out to you on the numerous times we have had these conversations. All of these models are numeric solutions.
of course they're numerical integrations. there is no general analytic solution, so it has to be a numerical method. lol i didn't say that they aren't using a numerical method, you're just too confused to know the difference. i'm saying that they're using a numerical method to simulate lots and lots of different initial conditions, and they're searching for initial conditions that lead to stable,
periodic configurations.
tbh i don't even get what your argument is anymore. you started with
numerical simulations of the solar system are impossible, and you've now arrived at
these are numerical simulations you ifiot!!!
Again, we see that these are numerical methods, and not based on an analytical solution. This argument is clearly and fantastically wrong.
lol. you don't have a clue what this is an image of, do you? that's awesome. please find more arenstorf orbits and post them. once again, literally no one but you is saying that there is an analytic solution to n-body problems. they're always solved with numerical methods.
Sandokan addressed Laskar here earlier this year: <pdfs>
unsurprisingly, sandy's author very selectively quotes
Newton's Clock to make it seem like Ivars Peterson actually agrees with him. he doesn't. i'm also not surprised that you haven't bothered to read any of this material yourself.
