[WIP][1.8.1, 1.9.1, 1.10.1, 1.11.0–2, 1.12.2–5] Principia—version Καραθεοδωρή, released 2024-04-08—n-Body and Extended Body Gravitation
The source code is available on GitHub under the MIT license.
Abstract
This mod aims to replace KSP's unstable physics integration with a higher-order symplectic integrator, adding n-body Newtonian gravitation in the process.

Principia is not built in the same way as most other mods (most of it is native code, with a thin C# interface layer), so that compatibility issues may arise depending on the platform.
Binaries are availabl
It has not escaped our notice that the specific physics computations we have implemented immediately suggest a possible extension to support angular momentum conservations. As a matter of fact, quite a few of the classes that manage parts, vessels and pile-ups were designed with this in mind: "if, in addition to position and speed, we also had rotation and angular momentum, then it would still work because...". We just never got to implement it. A bit of design will be required, but I think t
