Fictional celestial events are imaginative occurrences in space that do not exist in reality but are often depicted in literature, movies, and art. These events can include phenomena like supernovae that create stunning light displays, or black holes that warp time and space, captivating audiences with their dramatic potential. Such events can also involve mythical elements, such as comets that bring omens or planets aligning in rare configurations, leading to significant changes in a story's universe. These imaginative scenarios allow creators to explore themes of wonder, danger, and the unknown, enriching narratives with cosmic intrigue.
