Briefly describe why the detection of neutrinos coming from the Sun supports the theory that the Sun generates energy by nuclear fusion
What will be an ideal response?
Laboratory experiments and theory show that fusion reactions produce neutrinos. Therefore, scientists predict that neutrinos should come from the Sun if fusion is occurring in its core. Theories predict how many and what type of neutrinos should be observed. Thus, the observations that confirm this prediction support the theory.
