This mathematica notebook allows you to run animated numerical simulations of a test mass, or a photon in Kerr, Schwarzchild, Slow Rotating and Minkowski space time. By default the animation always displays a Black Sphere of radius 2. This has to be intepreted as the Schwarzchild radius for Black holes, and it must neglected when running the simulation in Minkowski.
You can change the following parameters directly in the interface,
- Choose massive or a massless particle for simulation
- Total simuation time
- Initial conditions
- Angular momentum of the Black hole, or spherical Mass
You can change the code to fix the range of spatial coordinates in the animation, right now it is set at Automatic.
