antognini: If anyone is interested in playing around with gravitational dynamics I highly recommend the REBOUND library [1]. It has a simple Python interface but under the hood it has a collection of research grade integrators. It came out around the time I was finishing up my PhD in gravitational dynamics, but if I were still in the field it's what I'd be using.If you're curious what would happen to the Solar System if you made Jupiter 10 times more massive you can pip import the library and find out for yourself in about five minutes.[1]: <a href="https://github.com/hannorein/rebound">https://github.com/hannorein/rebound</a>

antognini: 如果有人对玩引力动力学感兴趣，我强烈推荐REBOUND库[1]。它有一个简单的Python接口，但在引擎盖下有一组研究级集成程序。它大约在我完成引力动力学博士学位的时候问世，但如果我还在这个领域；这就是我所做的；d正在使用 如果您；你很好奇，如果你把木星的质量提高了10倍，太阳系会发生什么？你可以直接导入图书馆，在大约5分钟内找到答案 [1]：<a href=“https://；&#x2F；github.com#xx2F；hannorein#xx2F：反弹”>https://&#x2F；github.com&#x2F；hannorein；回弹</a>

pizza: If you want a good read that (to summarize it quite tersely) takes the idea of 3- or n-body simulations and goes very far indeed with it (i.e. why there is something rather than nothing), I highly recommend checking out Julian Barbour's The Janus Point.

pizza: 如果你想读一本很好的书（非常简洁地总结），它采用了3体或n体模拟的思想，并且确实走得很远（即为什么有东西而不是什么都没有），我强烈建议你看看Julian Barbour；s Janus Point。

nonfamous: This account has been posting simulations of interesting 3-body scenarios for quite a while. It used to be on Twitter but moved to Mastodon. You can check out the archives and play the videos, it’s quite neat: <a href="https://botsin.space/@ThreeBodyBot" rel="nofollow">https://botsin.space/@ThreeBodyBot</a>
