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@The_Lagrangian True, but it has low measure because it must evolve and does so rarely. Essentially is Boltzmann Brain problem1 reply 0 retweets 1 like -

@ConnorFlexman@The_Lagrangian Yes, it's a similar problem. But why do you think it has low measure?1 reply 0 retweets 0 likes -

@ConnorFlexman@The_Lagrangian My point is it doesn't have to "evolve", because you can just define an entire history from that fixed point.2 replies 0 retweets 0 likes -

@ConnorFlexman@The_Lagrangian And why should any universe defined like that exist more or less than any other?1 reply 0 retweets 0 likes -

@MoralOfStory@The_Lagrangian I see your point, and will have to think some. I think your assumption of single defined past is the problem2 replies 0 retweets 0 likes
@ConnorFlexman @The_Lagrangian I think the problem exists even if we allow multiple pasts. LMK if you solve it, we can compare solutions :)
