I don't agree. There must be an interference at this level. It just take place at a resolution or displacement (i.e. dimensionality) that isn't obvious and/or a non-trivial analytical problem teasing out. But it will be there. The carry-on by infinity theorists that it is not stands directly in contradiction of the current lynchpin for why a multiverse is...IS QM...and QM is....MULTIVERSE....(taken seriously you see). That would be the invariant universality of the wave function. At all scales, levels, universes and senses....except the one slit experiment where it isn't. That's actually a wave function collapse event too, you know. > > >> >> Then, is the one slit experiment isolating this universe in some way? >> > > There are an infinity of other universes in the one-slit experiment. > But say the incident photon has a certain frequency, that is a fixed > energy. > The detection screen then records only one photon of the same frequency > and same energy. > Thereby quantum collapse ensures conservation of energy. > The infinite number of other worlds still exist mathematically in the Math > Space of the block multiverse... > But a recalculation, like making a wrong turn, must be done in Math Space > to account for quantum collapse. > The need for continual recalculations may be the foundation of time. > Richard > >> -- >> You received this message because you are subscribed to the Google Groups >> "Everything List" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to [email protected] <javascript:>. >> To post to this group, send email to [email protected] >> <javascript:>. >> Visit this group at http://groups.google.com/group/everything-list. >> For more options, visit https://groups.google.com/d/optout. >> > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
