When did I claim I have 'special knowledge' of numerical simulations? By saying I can write them? They are very simple to do, any first year comp-sci major could write one, and easily wrine an n-body simulatort as well. It's not hard to do at all.
Since we have
contemporary sources saying that you are incorrect about Numerical Simulations, you're incorrect.
If you are going to argue something, you need to demonstrate it, not claim that you have special knowledge and have special credentials.

If you are going to argue something, you need to have more sources than a Wiki page you wrote. Please explain what in that page you are trying to use as an argument.
If posting a wiki link is a valid argument, I present
Three-body_problem as an example of a problem requiring numerical solutions.
I offered to demonstrate my abilities by writing code for you, you declined to take me up on the offer.
Again you are making your claims about 'special knowledge' and 'special credentials'. Knowing how to program isn't a special credential, it's simply a fact I have proven. Anyone who can program can write an n-body simulator.
I've posted actual star trails I took myself. They show circles. Your only argument is random pictures on the internet with unknown distortions.
