Going Deep Underground to Watch the Stars

Explore the fascinating world of neutrino astronomy in this 47-minute conference talk from the 35th Chaos Communication Congress. Dive deep into the design and construction of Hyper-Kamiokande, a massive underground neutrino detector planned for installation in Japan. Learn about the challenges of building a subterranean detector the size of a high-rise building and discover how it will help scientists unravel mysteries of the sun's core and supernova explosions. Gain insights into the ghostly nature of neutrinos, their ability to penetrate matter, and their potential to reveal information about otherwise inaccessible cosmic phenomena. Follow the journey from cavern excavation to photodetector design, and understand how this groundbreaking project will contribute to our understanding of solar physics, stellar evolution, and the origin of chemical elements essential for life and technology.
