In the near future, Earth is suffering from climate change, famines, and fundamentalism. A global nuclear war is imminent. Interstellar probes from the Breakthrough Starshot project initiated by J. Milner and S. Hawking have discovered a habitable planet in the stellar system Proxima Centauri, just in time for the exodus of the elites. On board the EXODUS starship, the crew starts to experience strange things. The voyage to Atlantis, the new home for mankind, enters a mysterious and disquieting territory, where conspiracy theories about what is real and what is virtual emerge. THE EXODUS INCIDENT is a novel about an interstellar journey, which connects science to virtual realities and epistemology. In the guise of a final investigative report, a scientific treatise discusses the physics and mathematics behind the story: the starship, the fusion thruster, the target planet, and the journey, addressing anomalous effects which involve relativistic speed and deep space environments.
