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.

  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.

  The arctan will cause some problems with the different quadrants, so if there is something like arctan2, that's better.

  For TPT, vx = -sin(arctan((vertical distance)/(horizontal distance)))*(Previous orbital velocity equation) and vy = cos(arctan(etcetera...

  Orbital velocity equation: velocity = (orbital velocity at one unit away)/sqrt(distance)

  if you look at in 7 display it looks liek a wormhole

  When you put a pressure bomb in the middle it will cause the galaxy it literally spin the swirly things (cant remember the name of them) around the black hole until it is sucked into the black hole.

  I put a big bang bomb in the center, and it looked beast lol

  if you put deuterium around the galaxy the galaxy will expand since deuterium is highly reactive in neutrons
