Are you sure that if we have a n-body system with n being very high, that it is not possible to distribute the masses, rotations, and distances in such a way that some mass/body somewhere in the system will be orbiting around a barycenter? I think that I read somewhere that when a galaxy is...
But according to fx. the animation from
http://en.wikipedia.org/wiki/Barycentric_coordinates_%28astronomy%29
then obviously the masses are orbiting around the barycenters!
But if some mass is somewhere in the fx. the milky way and no heavy masses are near, then shouldn't it be possible...
I suppose that you can say that the geometrical center of our solar system is the sun even though the barycenter do not align exactly with the sun!
If a lot of the total masses in our solar system were located far away from sun, then I suppose that the sun would still be the geometrical...
Has anyone tried to calculate the relative position of the geometrical center?
But couldn't it be that the milky way is constructed in such a way that position of the barycenter appears to fixed and that the idea of a black hole thereby is an illusion?
And even though the barycenter is...
My understanding is that if for example one object is orbiting another, then the mass center of the two masses is located somewhere in between the two objects. And if we have many object (for example stars), then the mass center of the total system can be located another place than were any star...
I agree that assembly language can be very tedious and also it is not very portable. But also it can be very fun. But maybe I have a bizarre way of having fun! And if Moore is right then I should have a heart, but no brain ... That is something to think about :-)
But according to the benchmarks then this GNU library can perform arbitrary precision pretty fast:

Also I think that a real good assembly programmer can beat any compiler by far or at least make code that performs just as fast, especially if using multiple cores in parallel...
@tony873004
It is a really cool project you are doing, and your calculation engines looks very interesting. Did you know that with wxWidgets then it is possible rather easily to write a program with a 'killer' GUI that can compile and run very fast on (almost) all operating systems!
You can...
Again thanks a lot for your deep insights. I agree to what you saying, but actually it is possible in for example C/C++ to extent to arbitrary precision as you can see here:

My experience is that if you use the newest processors...
Your program looks great and also it runs under Linux with Wine even though i couldn't find the Integrator menu that you have shown on the picture. Also I couldn't find any source code on your website. I personally prefer open source systems and also my program when it is finished one day will...
Thank you very much D H. Your answer seems very deep and profound, and it looks as a very good 'recipe' for what I need to make the program. I think that I better make the program in C/C++ as it otherwise will get to slow when I extend it to higher precision! Thanks.
Thanks a lot for your reply. Of course you are right, and I will design my program so that I easily can change the 'calculation engines' along the way. But now when I have started a thread about it then I would like to know what the best possible method is, so that I don't have to start another...
Thanks a lot for your reply. The link looks really great and even though I will build my program from ground up with a model as precise as possible then it might be worth figuring out the exercise (but it looks rather similar to another programming experiment I have been doing). But I think that...
