Analyze the distance between points using the Schwarzschild metric. GR Proper Length program simulates the distance between points using the Schwarzschild metric. It displays the proper length between two points and the light-travel path. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the gr_properlength.jar file will run the program if Java is installed.

GR Proper Length 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.
