Imagine nuclear fusion suddenly ceases in the Sun's core. How long would it take for us to discover the problem, and how could we discover it? How long would it take for us experience the negative consequences of this change, and why?
What will be an ideal response?
We could discover the problem within a few months using neutrino observatories, which would stop detecting neutrinos from the Sun. However, because it takes nearly a hundred thousand years for energy to travel from the core to the surface of the Sun, it would take approximately the same amount of time for us to start experiencing a cooling of the Sun.
