Spooky Action at a Distance

 

Spooky

In the cool of the evening when ev'rything is gettin' kind of groovy,
I call you up and ask you if you want to go and meet and see a movie,
First you say no, you've got some plans for the night,
And then you stop, and say, "All right."
Love is kinda crazy with a spooky little girl like you.

Maybe it wouldn’t seem so spooky if you understood it.

Einstein’s distaste for Quantum Mechanics came because of what he derided as spooky action at a distance, also know as Quantum Entanglement.  If you take two identical particles which are superimposed and separate them by a great distance, the measurement of a previously unmeasured attribute, such as spin, will have the same value in both particles, even if they have been separated by a distance that precludes transmitting that information at the speed of light.

For example, if one entangled particle is moved two light years from the other particle, it will  instantaneously have the same measured attribute as the other particle even though any information would take two years to pass from one to the other.  However if those two particles are superimposed, entangled, then they still have the same world line when transformed in Minkowski space.  If they are then separated in physical space, they are still on the same and NOT on different world lines.  If they have the same world line, then they are still the same particle, and of course will produce the same measurement.  If nothing has changed, then maybe spooky action at a distance is not so spooky after all.
