Cosmic events refer to significant phenomena or occurrences in the universe that often have a profound impact on the study of astronomy and astrophysics. These events can include supernovae, black holes, gamma-ray bursts, cosmic collisions, and other high-energy phenomena that shape the structure and evolution of the universe. Researchers study cosmic events to better understand the nature of the universe, the laws of physics, and the origins of celestial bodies. By observing and analyzing these events, scientists can gain insights into the fundamental processes driving the cosmos and the dynamic interactions between celestial objects.
