“Where is everybody?”: the question physicist Enrico Fermi posed to his Manhattan Project colleagues now 70 years ago. Decades of reaching out to intelligent beings elsewhere in the universe, and no response. Mont Babel sling-shots off the Fermi paradox using the opposing forces of a humanist father and an engineer son who rarely communicate. If they do, it is by email. They’re brought together by the lovely Iris Doubt, Tom Benedict’s south African geologist girlfriend, one of the Ariel School children who claimed to have been visited by aliens. Macrocosm meets microcosm in Mont Babel, quantum mechanics and astrophysics, neutrinos and black holes, raising questions about perception and consciousness, heaven and family peace.
