The collision between the Milky Way and Andromeda galaxies is a cosmic event that will happen over billions of years. Our simulation, powered by particle gravity simulators, provides a glimpse into this extraordinary event. As these two massive spiral galaxies converge, their gravitational pull will disrupt the orbits of stars and gas clouds, triggering intense bursts of star formation. While the individual stars within each galaxy are unlikely to collide, the overall structure of both galaxies
