When galaxies collide, several events can occur:

1. Galaxies merge: During a collision, the gravitational forces between the galaxies cause them to merge together over time. This can result in the formation of a new, larger galaxy.

2. Galaxies triple in size: As galaxies merge, they can combine their mass, increasing the size of the resulting galaxy. However, it is important to note that the actual change in size will vary depending on the specific galaxies involved in the collision.

3. Galaxies destroy their stars: During a collision, the gravitational forces can disrupt the structure of the galaxies involved, leading to the destruction of some stars. However, it is worth mentioning that not all stars will be destroyed, as some may survive or even form new stars.

It is important to note that galaxies disappearing is not a typical outcome of galactic collisions.

When galaxies collide, different events can occur. One possible outcome is that galaxies can merge. To determine which other events can happen when galaxies collide, we can break down each statement and analyze them:

1. Galaxies disappear: Galaxies generally do not simply disappear when they collide. They may undergo significant changes, but they usually do not vanish completely. Therefore, this statement is not correct.

2. Galaxies triple in size: While galaxies can experience changes in size when they collide, it is unlikely for them to triple in size. Collisions may cause galaxies to grow in some areas as their gravitational forces interact, but again, tripling in size is not a typical outcome. Thus, this statement is also not correct.

3. Galaxies destroy their stars: When galaxies collide, individual stars within them are not typically destroyed. The stars themselves may experience disruption or changes in their orbits, but outright destruction is rare. Therefore, this statement is not accurate.

4. Galaxies merge: This statement is correct. When galaxies collide, they have the potential to merge. Due to the gravitational interaction between the galaxies, their gas, dust, and stars get pulled together, resulting in the formation of a new, larger galaxy. This merging process can take millions of years, and the resulting galaxy may exhibit characteristics from both original galaxies.

In summary, the only correct statement in the given options is that galaxies can merge when they collide.
