EinsteinPy - Making Einstein possible in Python

EinsteinPy logo

EinsteinPy is an open source pure Python package dedicated to problems arising in General Relativity and relativistic physics, such as goedesics plotting for Schwarzschild space-time model, calculation of Schwarzschild radius for any mass given. Features like visualisation of geodesics of curved black holes and 3D visualisations are some of the features which are planned. It is released under the MIT license.

Key features of EinsteinPy are:

  • Geometry analysis and trajectory calculation in vaccum solutions of Einstein’s field equations

  • Schwarzschild space-time

  • Kerr space-time

  • Kerr-Newman space-time

  • Various utilities related to above geometry models

  • Schwarzschild Radius

  • Event horizon and ergosphere for Kerr black hole

  • Maxwell Tensor and electromagnetic potential in Kerr-Newman space-time

  • And much more!

  • Symbolic Calculation of various quantities in GR

  • Christoffel Symbols

  • Riemann Curvature Tensor

  • Simplification of symbolic expressions

  • Static Geodesic Plotting

  • Coordinate conversion with unit handling

  • Spherical/Cartesian Coordinates

  • Boyer-Lindquist/Cartesian Coordinates

And more to come!

Einsteinpy is developed by an open community. Release announcements and general discussion take place on our mailing list and chat.

The source code, issue tracker and wiki are hosted on GitHub, and all contributions and feedback are more than welcome. You can test EinsteinPy in your browser using binder, a cloud Jupyter notebook server:

EinsteinPy works on recent versions of Python and is released under the MIT license, hence allowing commercial use of the library.

from einsteinpy.plotting import StaticGeodesicPlotter
a = StaticGeodesicPlotter(mass)
