This is one of the projects in the course of Computational Physics and Finite Difference Analysis (FDA) that I find pretty interesting. In the diagram below, each galaxy is assumed to consist of 1 core only, along with multiple, users’ defined number of stars. In this simulation, only core exerts gravitational force on stars, while stars do not contribute to any particles’ interaction in galaxy(s).

For a single galaxy (moving in one direction at constant speed) as an example, the following gif should be sufficient to demonstrate its fundamental behavior.

Since galaxy collisions depend heavily on initial conditions, here I’m presenting two collision examples. In each example, there are two galaxies with 5000 stars each. Frankly, after this project, I start to appreciate the beauty of the universe and physics.
