Omega: The Last Days of the World, published in 1894 by French astronomer Camille Flammarion, is a speculative science fiction novel exploring humanity’s fate in the face of cosmic catastrophe. Combining scientific theory with philosophical reflection, the story imagines a comet threatening Earth and the varied responses of societies and individuals. Flammarion blends astronomy, eschatology, and spiritual inquiry, creating a thought-provoking meditation on impermanence, human progress, and the universe’s mysteries. It’s a foundational text in cosmological fiction.
