Orbital motion causes a winding effect in a collection of free-falling objects; Parts 5 & 6 also show this unintuitive behavior.
This is the familiar “textbook” phenomenon caused by gravitational tidal forces.
If the simulation software produces accurate behavior, the middle row should produce a circle.
If the simulation software produces accurate behavior, the top & bottom row should produce lines.
This is a previously obscure phenomenon; it is caused by a synthesis between
the same gravitational tidal forces in (2) and the kinematical principle in (1).
This simulation implies a connection between galactic orbital motion and the winding number of a spiral galaxy’s arms.
This simulation demonstrates that the same code that produces the foregoing simulations, produces Keplerian elliptical orbits.
