Question

Quizplus · Accepted Answer

Neutrinos are a product of the fusion reactions that occur in the core of the Sun. If there were no more neutrinos coming from the Sun, it would mean that the fusion reactions have stopped. Option B is unlikely because it would take hundreds of thousands of years for the effect to reach us. Option C is incorrect because the Sun does not undergo fission reactions. Option D is also incorrect because the Sun does not have a finite supply of neutrinos.
