[Marvel] If it was somehow possible to permanently satisfy the hunger of Galactus and end his constant need to find new planets to consume, how would he then spend his time?

He is a scientist and explorer, or at least he was before he became galactus. So he would be free to travel the world and learn. Perhaps he would become like the Watchers and take an oath of noninterference, or maybe like the Beyonder and influence the world as to help it. 

Though, depending on how his hunger was satisfied he might still eat planets. His original purpose was to collect enough energy to form a new universe when this one dies. Even if he doesn't need to eat planets, he might choose to do so for the greater good.
