This astronomy simulation presents stars in their Altitude/Azimuth coordinates serving as an introduction to the celestial globe and equatorial coordinates.

Users have the opportunity to adjust several variables in this simulation demonstrating the Ancient Greek's Two Sphere Universe theory.

Simulation examining simultaneity and causality in special relativity by manipulating the space and time coordinates of one or two events.

The path of cannonballs fired near a black hole are computed using the Schwarzschild metric and presented in this visualization, allowing for study of the theory of general relativity. The cannon's angle and the number and speed of the...
