Particles' positions and colors were calculated with a Lua script I put together. View with decorations enabled (preferably also with viewing mode 8) and unpause to watch the gravity diffuse the galaxy into a cloud of particles orbiting a central mass.

    Looks like an actual gravity +1

    Remove the void and gpmp in the middle and you get a black hole simulation +1

    Using the console, try setting the gravity pump's temperature to between 270 and 300 K so that the mass of the central hole changes and makes the galaxy more weakly or strongly attracted. The changes should make the simulation should play out differently and show things such as tighter orbits or a complete dissolution of the galaxy.

    yeah ok but call it galaxy simulation 2

    Should I change the galaxy into a spherical cloud now? Perhaps I can make it an elliptical rather than a spiral.

    @Skitz: the formula that I used for orbital velocity works in a similiar simulation I made in Gamemaker, guessing around at the unknown variable (orbital velocity at 1 unit) was pretty easy.

    looks better on 8. and no i dont read the description!

    More like a globular cluster, assuming that every perticle is one star.

    I used something I found more simple. I wish I could give some more psuedo-code, but it is not very easy trying to type into a comment box. I gave polar offsets (offsetX and offsetY) and got the velocity magnitude with a real formula (orbitVelMag = sqrt((G * M)/orbitDist)) where the mass (M) was just something random.
