Which of these events can happen when galaxies collide?(1 point) Responses Galaxies triple in size. Galaxies triple in size. Galaxies disappear. Galaxies disappear. Galaxies merge. Galaxies merge. Galaxies destroy their stars.

Galaxies merge.

When galaxies collide, several events can happen:

1. Galaxies merge: The gravitational forces between the galaxies can cause them to merge together. This can result in a new, larger galaxy formed from the combination of the original galaxies.

2. Galaxies triple in size: When galaxies merge, their overall size can increase, often resulting in a larger and more massive galaxy compared to its original components. However, it is not common for galaxies to exactly triple in size.

3. Galaxies disappear: It is unlikely for galaxies to completely disappear during a collision. However, the individual structures and features within the galaxies may be disrupted or rearranged as a result of the collision.

4. Galaxies destroy their stars: While galactic collisions can have a profound impact on individual stars within the galaxies, it is not correct to say that galaxies destroy all their stars during the collision. Some stars may be ejected from the galaxies, while others may be disrupted or torn apart. However, many stars can survive the collision and remain within the merged galaxy.

When galaxies collide, several events can occur. One possible outcome is that the galaxies may merge. This happens when the gravitational forces between the galaxies cause them to combine and form a new, larger galaxy. Another possibility is that the galaxies triple in size. While this is not a common outcome, the collision can result in the expansion of the merged galaxy. On the other hand, galaxies disappearing or destroying their stars is less likely. When galaxies collide, their stars may undergo gravitational interactions, but it is rare for entire galaxies or their stars to vanish or be destroyed as a direct result of the collision.
