The GR Kerr Light program simulates the path of light in the equatorial plane near a rotating Black Hole using the Kerr metric. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the gr_kerr_light.jar file will run the program if Java is installed. The Default setting is light with an initial r value of 3.0 near a black-hole with angular Momentum parameter, J/M = 0.75. GR Kerr Light is part of a suite of Open Source Physics programs that model aspects of General Relativity. Other programs provide additional visualizations. They can be found by searching ComPADRE for Open Source Physics, OSP, or General Relativity.
