Early solar neutrino experiments detected only about a third of the number of neutrinos predicted by the theory of fusion in the Sun. Why didn’t scientists simply abandon their models at this point? What features of the Sun did the model get right? What alternatives were there for explaining the mismatch between the predictions and the observations?

Briefly describe the Moon’s cycle of phases. Can you ever see a full moon at noon? Explain.
