Cosmic Collisions

The passage examines what happens when galaxies collide, describing these interactions as slow, graceful encounters influenced by gravity. It explains how galaxy collisions can lead to the merging of two galaxies over millions of years, resulting in new, larger galaxies. The passage also highlights how gravitational forces shape the structure and movement of galaxies during collisions. It concludes by emphasizing the ongoing process of galactic interactions in the universe.

This passage introduces students to vocabulary associated with cosmic interactions, such as “gravitational attraction” and “merging.” It enhances comprehension by breaking down the slow, gradual process of galaxy collisions. The passage encourages critical thinking as students consider how these collisions impact the formation of new galaxies. Lastly, it builds reading proficiency through its detailed, multi-step explanation of cosmic events.
