Galaxy- Stellar Simulation

Galaxy is a computer program which simulates the motion of stars under the influence of gravity. Create a field of random stars to begin with, then watch the stars move as they are accelerated by their mutual gravitational attractions. You can vary the number of stars and the strength of gravity. Watch how the attractive forces accelerate individual stars and send them careening in new directions. Watch how large groups of stars develop into interesting patterns over time, such as clusters and spiral arms.
