In Search of Green Dwarfs
As kids know well from this experience, the question of “Where to look?” is more urgent than “What exactly are we looking for?” The simplest strategy is to search in places where the afikoman was found in the past. This is exactly the strategy adopted by astronomers in the search for extraterrestrial life. Their current search strategy focuses on rocky planets in the habitable zone of stars, consistently with the only place where life has been found so far: Earth.
