Galactic collisions mostly involve interactions between gas and dust clouds rather than individual stars.

Question

Quizplus · Accepted Answer

Galactic collisions are vast in scale, and the distances between stars within galaxies are so large that direct star collisions are extremely rare. Instead, these events primarily involve gravitational interactions that affect the gas and dust clouds within the galaxies, leading to new star formation and other complex dynamics.
