life is very rare indeed—but it is not impossible. Taking into account both the distribution of universes and the likelihood that things like planets and stars will form within a given universe, Weinberg and others have calculated how much dark energy typical observers should find to be present in their universe. Intriguingly, they find that the most common places for life to emerge are those corners of the multiverse in which there is roughly as much dark energy as there actually is in our world. In this sense, the existence of the multiverse resolves the long-standing mystery of dark energy.
