Solar neutrinos:

Quizplus · Accepted Answer

Solar neutrinos are elusive particles produced by nuclear reactions in the sun's core that can provide important insights into the processes that power the sun. Neutrinos have the unique ability to change their identities en route to Earth, a phenomenon called neutrino oscillation. This property makes it challenging to detect them and accurately measure their numbers. The detection of fewer solar neutrinos than predicted by initial theoretical estimates led to the discovery of neutrino oscillation and the subsequent recognition of the need to revise our understanding of neutrino physics. In 2002, the Super-Kamiokande experiment in Japan detected solar neutrinos in the expected numbers, validating the theoretical predictions at low energies. Since then, other experiments have confirmed these measurements and provided further insights into the mechanisms associated with solar neutrino production. Overall, solar neutrinos are a powerful probe of the proton-proton chain, the dominant energy source of the sun, and a crucial tool for testing our understanding of fundamental physics.
