Fictional cosmology refers to the imaginative frameworks and universes created in literature, film, and other media. These constructed realities often include unique laws of physics, diverse species, and intricate histories that differ from our own. Examples can be found in works like J.R.R. Tolkien's Middle-earth or Isaac Asimov's Foundation series, where the settings are meticulously developed to enhance storytelling. In fictional cosmology, creators often explore themes such as the nature of existence, the role of deities, and the fate of civilizations. These narratives can reflect real-world philosophical questions while allowing for creative freedom. Notable examples include George Lucas's Star Wars and C.S. Lewis's Narnia, which offer rich, immersive worlds for audiences to explore.
