Quantum Entanglement

 

Spooky

In the cool of the evening
When everything is getting kinda groovy
I call you up and ask you
Would you like to go with me and see a movie
At first you say no you've got some plans for tonight
And then you stop and say, "alright"
Love is kinda crazy with a spooky little girl like you

Maybe it isn’t so spooky after all?

Given the Heisenberg uncertainty principle, and the superposition of particles, isn’t quantum action at a distance inevitable, not spooky.

For example, take a deck of cards.  Divide them into one deck of red cards and one deck of black cards.  Turn the two decks over and shuffle them so that you can’t tell which deck is which.  Pick two cards from one deck but do not look at them.  You do not yet know the color of the card. Now look at the first card.  If it is red then that means that every card in its deck was red.  Now if you look at the second card, it is ….surprise, surprise…. red.  There was no need for communication between the first and second card. Any distance separating the cards is irrelevant. By observing the first card, which had not yet been observed, you could be certain of the color of the second card.  This isn’t spooky, it’s statistics.

Schrodinger’s cat, before it is observed, has odds of being 50% alive or 50% dead.  But the unobserved odds have nothing to do with the cat.  The cat will be either 100% alive or 100% dead but you will not know until you open the box, observe it.  The odds are NOT the result.  The odds of a coin flip are 50% heads.  But the result of every coin flip will be either 100% heads or 100% tails. There is nothing spooky about that.
