Top 3 general-relativity open source projects

Python package for computing Kerr quasinormal mode frequencies, separation constants, and spherical-spheroidal mixing coefficients

Non-spinning black hole simulation based on geodesics equation

Solar System Simulator written in Java. Positions and velocities of 30 solar system bodies and 3 spacecraft are continuously updated using either Newton mechanics or General Relativity. Initial positions and velocities are obtained from Nasa JPL's ephemerides. While simulating, both simulated positions and ephemeris data are visualised for compa…
