If a unmeasured electron or any particle (the exparament was originally done with silver atoms) passes through a Stern Gerlach magnet the particle will be deflected up (relative to the orientation angle chosen to set the magnet at) or down 50% of the time. And if 2 electrons are quantum correlated and one is found to be deflected up then there is a 0% chance the other electron will also be deflected up. The really weird thing is that the direction I chose to be called "up" was completely arbitrary, I could have picked anything from 0 degrees to 360 degrees, and yet it's brother electron seems to instantly know what angle I chose to call "up" even though they are now 2 million light years away and the brothers were last in physical contact with each other a million years before I was born. *>However, if you replace "John" with large numbers of Johns, "Jason" with > large numbers of Jasons, and photons with "large numbers of correlated > photons", then there is no need for spooky action at a distance.

The reason I like Many Worlds is that to my mind universes splitting is slightly less spooky than alternative explanations for bazaar facts we find with experiments, but only slightly. That's why I say if Many Worlds isn't true then something even weirder is. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
