My understanding of MWI doesn't go much beyond what I could understand of an early Wheeler paper (I thought it was from the mid-40s, but Wikipedia says MWI starts with the thesis of a student of his with the first publication in 1957 ... and I read that paper (whenever it was published) 25 years ago so it's gotten pretty fuzzy). Well, in this universe it started in '57. In yours, it seems, it is different. Where are you from traveller ?
