that must be an error.


Add in the next three words and read it again

"two particles don't entangle with each other therefore the two particles entangle with each other and the background"

Sorry that English thing again let me draw the two options

(1) Particle <-- entangle --> Particle

(2) Particle <-- entangle --> universe background <-- entangle --> Particle

The wiki entry tries to describe entanglement and as best it can it does so ... what it doesn't discuss is the why which is what we have been discussing.

which directions were the particles emitted?
did the containment coils or whatever held the particle centered as it traveled build any magnetic field that might have spun the particle in different directions.

I know why it had two different spins if it was a north to south or a east to west travel does not matter as long as
there were two different directions of travel.


were there two different directions of travel?


The orginal works with entanglement where all based around John bell's work from 1964.

You will find extensive discussion of the test in wiki including important key retests of the result from 1969-2009.
They entangled different spins in different setups and different ways testing all the sorts of suggestions you made and many many more.

The whole question become moot in 2009 because science managed to be able to entangle two electrons and have the two electrons under test at the same time because they have charge.

Here is the write up on the first experiment

To many who liked the EPR argument it was a death blow because electrons are considered part of the solid matter regime.

It got even worse because we continued to take entanglement out into more and more particles and then eventually molecules considered solid matter.

In 2010 entanglement was extended out into a macro visible object

In 2011 this was expanded to very large vessels of gas

It's so boring and mundane and experiment these days most university students will do it as part of there physics class

Here is Berkley universities student coarse

And if you don't believe us and want to do the test a home a mere $7500 USD will get you a home kit

This is sort of what I was saying to Bill that pre-2009 his thoughts were probably semi-acceptable but post 2009 that is a very hard position for any scientist to support.

Yes all the experiments are done an earth and because we are trying to exclude everything to satisfy the EPR zealots sometime very soon science is going to try an entanglement between earth and the ISS.

This should also set a new record for a distance and if QM is right the required faster than light communication speed you proposed is going to be pushed up even higher.

China may actually beat everyone to do this because there is a sort of quantum arms race going between USA and china over this.

The two nations are locked in a Quantum arms race because the military wants it for secure communication because there is no wave or transmission that another foreign power can intercept or eavesdrop on.

There are now literally thousands if not millions of experiments that show the entanglement and that's why you won't find any scientists saying the behaviour doesn't exist.

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
