Why does the Sun get brighter with time?
What will be an ideal response?
As the Sun gets older, it converts more of its hydrogen to helium. As the He content increases, the sun's core becomes denser. This density change leads to a higher temperature within the sun, causing nuclear fusion within the core to proceed faster. The faster rate of fusion leads to a greater luminosity.
