Study black holes with the help of this simulation. Particle Worldline model computes and displays the trajectory of a test particle in the vicinity of a black hole using Schwarzschild coordinates. It was created for the study of Einstein's theory of general relativity and the Schwarzschild metric.

The model has input fields displaying the Schwarzschild coordinates and their rates of change as well as the energy E and and angular momentum L of the particle. Conservation laws and the speed of light impose restrictions on the dynamical variables and these restrictions are enforced when entering values or dragging the particle. For example, if a user changes the default value of dr/dt to 10, the model automatically reduces the value to 0.685 because the particle speed cannot exceed the speed of light c=1.

The Particle Worldline model computes and displays the trajectory of a test particle in the vicinity of a black hole.?It was created for the study of Einstein's theory of general relativity and the Schwarzschild metric. The main window displays a map of space in the vicinity of the black hole using Schwarzschild coordinates. The azimuthal angle f is defined as the ratio of the arc length to circumference of a circular path centered on a black hole with mass M=1.
