The Neutrino: Mysterious and Elusive

Ghost Particle explores the neutrino, one of the most abundant yet elusive particles in the universe, tracing its journey from a theoretical fix to puzzling nuclear reactions to a cornerstone of modern physics. The book explains how neutrinos helped preserve fundamental laws like conservation of energy and reveals how decades of ingenious experiments finally confirmed their existence. The authors guide readers through discoveries such as neutrino “flavors,” oscillations, and the surprising realization that neutrinos have mass—challenging the Standard Model of particle physics. Cutting-edge research is connecting neutrinos to cosmic phenomena, including supernovae, the interior of the Sun, and the structure of the galaxy itself. Neutrinos may unlock answers to some of the universe’s deepest mysteries, from the imbalance between matter and antimatter to the nature of dark matter and dark energy.
