Cosmic Neutrinos

Neutrinos were produced in the early universe and are currently the most abundant form of matter. What can we learn from these cosmic neutrinos? Upcoming surveys will provide information crucial to some of the key questions in fundamental physics such as: What gives neutrinos mass? What is the pattern of their masses? Are there extra neutrinos that do not interact with other particles but are sterile? Current observations have begun this cosmic exploration; the future of cosmic neutrinos is even more exciting with several large surveys due to begin before the end of the decade.
