This clip shows two galaxies colliding, each galaxy contains 3 Million stars. The software uses the gravity equation F=G*M1*M2/R^2 and assumes that orbiting stars have negligible mass compared to the super massive black hole at the center. The app is written in CUDA and runs on the GPU at about 20 frames a second on my nvidia 88000GTS. That equates to about 120 million particles per second. The first simulation shows the collision of two spiral galaxies. The second simulation shows the ...
