While this may sound catastrophic, the vast distances between stars mean direct collisions are unlikely. Using advanced particle gravity simulations, we can visualize how this cosmic event will unfold. As the two spiral galaxies draw closer, their gravitational forces will distort their structures, disrupting star and gas cl
