... However, we should be able to tell that the hydrogen fusion in the core has stopped by observing the solar neutrinos. The neutrinos do not interact with the solar plasma, and can escape the Sun and reach Earth in about 8 minutes. So, we would find that the neutrino flux is decreased. 2. Chapter 11, ...
