This idea that matter can "communicate" across great distances through "spooky interactions" creates an almost endless number of possibilities, from the religious to the supernatural to the realm of science fiction. At a minimum it suggests that any smugness people have about thinking they know what constitutes the fabric and texture of existence is ill founded.

It's stuff like this that makes my head spin.

According to quantum mechanics, particles do not take on formal properties until they are measured or observed in some way. Until then, they can exist simultaneously in two or more places. Once measured, however, they snap into a more classical reality, existing in only one place.

Someone explain how we can know something exists without observing it? If something can exist on more than one place on a atomic level until we observe it, why then can't something on our level exist two places? Perhaps we just can't observe it yet.

Maybe that's what ghosts are ....

That part got me too, almost posted it like you did.

Let's see, it can be anywhere till measured
Then it's pinned to one place.

From a more practical standpoint I view most physics as models.

All models are wrong , but some are useful.

In a physics class I remember a discussion about the possibility of building a teleported like in Star Trek. The professor said that while transporting a single atom would be one thing, but think about how many atoms make up a person. Then add the fact that they have to all be arranged in a particular way. I think somewhere in there is part of the answer to Funkys question.

Spooky action at a distance, Einstein's thought on quantum entanglement. He could not believe in quantum mechanics because "physics should represent a reality in time and space."

Im with you. Logically I think they have it wrong. Just because we havent observed it yet, doesnt mean it doesnt exist. Upon observation the thing itself isnt altered. Its just observed.

But what do I know. I certainly dont claim to be any sort of expert.

What if the particle was observed simultaneously in two separate locations?

Has that happened? I don't know, but my limited research says that it hasn't, yet.

It's funny how we always try and postulate things that are so 'far away' in time, space and magnitude from our own, while a large percentage of the world can barely grasp the most simple scientific concepts. Maybe if our best and brightest researchers took a break and went into some classrooms and adult ed. places, they'd have a bigger impact on the world. Or they'd blow their brains out. (Cancer guys can continue working, thanks.)

I can't tell if you are talking smack or not.
