Does the universe have a handedness? According to this Spiral Galaxy Study it does. If so, was there more right-handedness before the BB or did this only happen due to the asymmetric nature of the BB event? I guess that 2/3 of matter could have been right-handed to start with, while only one out of the three spatial axes could have been left-handed. (Think about it). This seems a likely contender to me.
