Which would be more likely to collide: stars with stars or galaxies with galaxies?

Answer 1

Collisions between stars are rare.

Since many galaxies are found in groups or clusters, it is not surprising that there are occasionally collisions between them given the large number of galaxies found in these formations.

While collisions within galaxies are common, star-to-star collisions are extremely uncommon because stars in each galaxy are so far apart.

Answer 2

Because of the vast distances between galaxies and the relatively compact spacing of stars within a galaxy, collisions between individual stars within galaxies are far more common than collisions between entire galaxies.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
