If we ascribe an observer in all of this, then we raise the obvious questions: who is the observer, and when did the observation occur? The answers may be, as surprising as it sounds, we here and now.
By peering back in time, by looking out into the universe at light signals that were emitted millions and millions, perhaps billions and billions of years ago, we may be the observers that are causing the early universe to split, and thereby we are choosing by our observations today what the radius and other physical parameters of the early universe were.”1
