We're fascinated by things we can't figure out, by the things that don't have a right or wrong answer. Even when we can't explain them, we need to make some sort of sense out of them - create lists, find connections, map it out. Maybe that's why, when we can't seem to figure out all sorts of other more commonplace mysteries (like why we all keep looking at the sky as if it might talk to us), we still need to try.We think maybe it's a lot like love, that need to make sense of the sky. We don't know why we need it, we can't explain it when it happens or when it doesn't, but we need it like we need air or food.So we keep looking for it.
