Software to simulate how objects move and interact under the force of gravity.

AstroGrav is an astronomical software program that allows you to simulate how astronomical objects move and interact under the force of gravity. It features superb interactive 3D visualizations that allow you to move around within a many-body astronomical system, while watching how it evolves with the passage of time. A wide variety of sample files are provided, including solar system, space mission, exoplanet, and abstract systems, and these enable you to experiment with the software without having to enter your own data. The comprehensive editing facilities allow you to either create your own astronomical systems, or to modify existing ones, and provide you with an almost endless scope for experimentation and investigation.
AstroGrav can be used to visualize and understand the following aspects of gravitational systems and astronomical systems.

AstroGrav calculates how astronomical objects move according to Newton's Law of Gravitation, and displays the results as they are calculated so that you can watch the system evolve as in a movie. The software is very accurate, dynamically calculates orbits as a system evolves, deals correctly with object collisions, and can cope simultaneously with objects on many different timescales. AstroGrav also includes an option to use Einstein's General Theory of Relativity in situations where Newton's Law of Gravitation is inadequate.
