Abstract Systems

The following simulations are a variety of abstract systems that can be studied, modified, and used as a source of ideas for further investigation.

Collapsing Cloud shows a cloud of 100 identical objects that are initially stationary.
Globular Cluster Collision shows two globular clusters on a collision course, each containing 401 identical stars.
Globular Cluster shows a globular cluster of 401 identical stars.
Many Body System shows many massive stars orbiting a much more massive central star.
Projectile shows the Earth together with a single projectile.
Protoplanets 2D - 1 shows a central star together with 400 identical protoplanets.
Protoplanets 2D - 2 shows a central star together with 400 identical protoplanets.
Protoplanets 3D - 1 shows a central star together with 400 identical protoplanets.
Protoplanets 3D - 2 shows a central star together with 400 identical protoplanets.
Spiral Arms shows a galaxy in which the core is represented by a single large object, the rest of the galaxy is represented by a disc of 1,000 stars, and a second galaxy is represented by a single massive object.
Three Body System shows three similar objects, with two objects orbiting each other in a close circular orbit, and as a pair orbiting a third object in a much larger and eccentric orbit.
Two Body System shows the simplest simulation of interest - a two body system with one body orbiting the other in an eccentric orbit.

The descriptions of the more complex systems include details of how they were created, which can modified to create similar systems.
