The space between stars in galaxies is so great that when galaxies collide there are hardly any collisions if any at all between stars.
@evilscientistca Thank you for sharing your knowledge and drawing attention to science. What program was used to create the post’s animation?
@jaller94 the data was created with a Barnes-Hut simulation on the Swinburne supercomputer. The individual frames were created with GNUPlot. I can't remember what software I used to put them into an animated GIF.
@jaller94 I'm currently mucking about with the data and Blender to see if I can make it more 3D.
@evilscientistca Thanks for the insight. And it’s fascinating to see a dataset from a super computer being rendered in the powerful and open GNUPlot software.
