Galaxy

Just a little fun one because I've finished my exams and I haven't had time to start any big projects yet. A bit of very simple inverse square law gravitational physics to simulate the sombrero galaxy. All orbiting stars are attracted to the centre of the galaxy by an amount proportional to 1 over the square root of the distance between them.

Just click the two images below to launch the 2D and 3D simulations! Enjoy.

The three examples below show that with slightly different initial conditions, the shapes we find in a simple galactic simulation like this one, are actually surprisingly similar to those we see in real galaxies, for example in the first you can almost see the emergence of the spiral arms of our own galaxy the Milky Way.
