We can easily calculate whether or not the final habitable zone can ever extend far enough for this to be possible.
WebThe only case in which a white dwarf can reignite is a nova. This is when a very close companion star starts funneling hydrogen onto the surface of a white dwarf. At some point, a critical pressure of hydrogen is reached, and the whole thing begins fusion at a very fast rate, shining very brightly for a few weeks before fading again.
