A Bridge between Worlds: Parallel Universes and the Observer in “The Celestial Plot” by Adolfo Bioy Casares

Adolfo Bioy Casares’s story “The Celestial Plot” (1948) is among the best known examples of Latin American science fiction writing of the early twentieth century inspired by contemporary advances in quantum physics. Most readings of the story focus on the movements of its main protagonist, Captain Ireneo Morris, as he traverses realities while test-flying a plane. This approach overlooks the role of the story’s other protagonist, Dr. Carlos Servian, who, we argue, is the lynchpin upon which the multiple realities are dependent. We read the changes to Dr. Servian’s character from a variety of scientific and philosophical perspectives on parallel universes. By addressing variations in Servian’s character and language, and focusing on the disparate representations of the key objects in the story, we show how the story anticipates in some ways the Many Worlds notion which argues that reality bifurcates during quantum measurements, leading to near-identical copies of observers.
