Einstein Cannon Model

Jan 25, 2011

The Einstein Cannon model was published as a supplemental simulation for the article "When action is not least for orbits in general relativity" by C. G. Gray and Eric Poisson in the American Journal of Physics 79(1), 43-55 (2011).  The model computes and displays the trajectory of cannonballs (particles) shot from a cannon in the vicinity of a black hole.  It was created for the study of Einstein's theory of general relativity and the Schwarzschild metric.
