Every possible state in QM uniquely defines a past & future. Many possible QM states include a copy of you. Why do we observe a single past?

@MoralOfStory I suspect answer is the same as for "why do we observe a single future", which is to chant "decoherence" while waving a stick2 replies 1 retweet 2 likes -

@The_Lagrangian@MoralOfStory My impression is to point toward information entanglement: we only gain information through time, not lose1 reply 0 retweets 0 likes -

@MoralOfStory I am confused by this argument. If you take a state and "cut&paste", you are talking about an entirely separate universe1 reply 0 retweets 0 likes -

@MoralOfStory it asks the question "what would happen in a universe w/ different boundary conditions that happen to agree on tiny patch"1 reply 0 retweets 0 likes
@The_Lagrangian Yes, that's the question. It seems most theoretical copies of us would exist in such a situation?
