Read about this recently.

My mind is boggled, my gob is smacked. I have a headache.

Apparently it is possible for one partical to be affected by another partical as if they are joined together - [b]even if the particles are in another part of the universe, millions of miles apart[/b]..

In other words, if you had 2 related particles - one in your hand and another in someone elses hand in another galaxy - if one was made to vibrate then the other one would as well, inspite of the distance between them..

I appeal to resident PH nerds and science boffins to explain this.

Apparently it is going to be a big deal as scientific discovery continues.

More here :

http://www.abc.net.au/science/features/quantum/

It is described even on this science site as "bloody confusing" and by all accounts even Einstein " had a bit of trouble with it.."

If it is such a big deal, I want to understand it. Help please...:rolleyes:

If Einstein had trouble with it I'm not going to even bother.

This just too hard to explain in the forum. Do a search for 'Bells inequality'. Then read Deutch's 'The Fabric of Reality'. Then we can take it from there.

Awww...c'mon...

It can't be that hard.

I need someone to summarise it for me. Put it in a nutshell.

Someone??

There are some bits of Physics that you just need to leave to the Hawkings and Einsteins of the world. Trying to understand it will just give you a headache (no offence!).

I work with very specialised microscopes. One type in particular relies on electrons jumping from one place to another. Except that they don't really jump, they disappear from one place and appear in another without having been anywhere in between. Don't ask me to explain it because I don't know!

I heard a great quote the other day from someone who had won a Noble prize for physics or something.

"If I could explain it in laymans terms, I wouldnt have deserved it"

Now stop it.

Thats just silly.

If an electron can do that, what stops larger particles doing the same thing? In which case, why can't I travel to another place instantaneously?

See? You can't . Prove that your point is just silly. They only told you that at Uni. They were pulling your leg mate....

Actually you could. Unfortunately your wavelength is so small (associated with Planks constant and your mass) the likelyhood of you moving a measurable distance is truly minute.(unlikely within the lifetime of the universe. Really small particles are more free to do it as their mass is tiny compared to macroscopic objects such as yourself.

This theory has been around for a few years now.

It is suggested that it can be used to create communication systems that work instantly across hundreds, thousands or even millions of lightyears.

It is also thought that it could lead to the artificial creation of wormholes.

If you want to ask or discuss this with some real experts, try the forums at www.space.com - many Nasa employees use them along with your genuine rocket scientist.

The reason you can't do the same thing as the above mentioned electrons is because an electron is a sub-atomic particle and you are not (I assume!).

Electrons are bound by the laws of Quantum physics whereas you are bound by the laws of macro physics (or whatever the correct term is). The two are very different. So far as I understand it, the holy grail for the science bods is to combine these two apparently conflicting sets or rules into a 'theory of everything'.

Of course that might all be rubbish...

A profound understanding being exhibited here. But you missed out the flapping butterflys causing the congestion charge.

Toppstuff, panties are the key to unlocking the ERP paradox...

J Orlin Grabbe said:
The job was fun. It gave you that primitive feeling, out here on the street, following two females with original sex parts. It was exciting, kinky as it was. I followed them into the crowded bar of a place called Carolina's. One of them had short black hair that curled in around her face. Not badly shaped, but a bit thin for the current season. Not so the blonde. She was a couple of inches taller and ripe in all the right places.

I maneuvered my way up to the counter, so I could hear what they were saying. It was difficult not to appear obvious in the small room. By turning slightly as I sipped my gin and tonic, I could look down the neckline of the blonde's cream-colored dress, and trace the curve of her breast almost to the nipple. It was real, all right. I thought about her other real parts. The short one with dark hair was talking. And let me tell you. This is really the way it happened. I got the memory, you see. Make no mistake. This is what Short-Dark said:

"There are these two sisters, see, Carol and Joyce who always wear either red or black panties. They start out in New York, and Carol flies to London while Joyce goes to Los Angeles. Carol then picks up this guy in a singles bar and takes him back to her hotel. She removes her dress and the guy observes she's wearing red panties. Instantly he rushes to the phone and calls his friend in L.A., who all this time has been with Joyce. The two of them are laying in bed in post-coital bliss-out, and he casts his gaze at the tangled clothes strewn across the room, and sure enough, Joyce's panties are seen laying over on the couch, and they're black.

"On another occasion Carol flies on to Bangkok, while Joyce goes to Honolulu. The same thing happens. Only this time Joyce's panties are red, but Carol's are black. The key fact is that no matter what color panties the first sister is wearing when seen by a lover, the other sister is wearing the opposite color." I ordered myself another gin and tonic. I sure liked the way these sex primitives talked. Short-Dark kept at it:

"The question is, how did the observation of the first sister's panties force the other sister's underwear to have a different color? It proves that information transfer is instantaneous. Or, as physicists would say, that reality is non-local."

"Or that someone has a large phone bill," Blonde responded.

Short-Dark continued: "Non-local means one thing here causes something else to happen over there, with nothing in between. In physics, the observation that the colors of the panties are always different despite the displacement of the two sisters in space is just one more illustration of the Einstein-Rosen-Podolsky Paradox. It's similar to a conceptual experiment Einstein used to show quantum mechanics must be incomplete, because otherwise information transfer would have to take place instantaneously. That is, faster than the speed of light, which Relativity said couldn't happen. The only problem is that the experiment has now been performed numerous times--using elementary particles--and the panties are always of different colors. So information does in effect travel faster than the speed of light. Bell's Theorem implies the blunt conclusion: reality is non-local."

"Next you'll tell me about Mother Bell's Theorem, which undoubtedly concerns sex-at-a- distance."
"I tried phone sex once," Short-Dark replied, "but the handset was the wrong shape and I never got off. Another way to view Bell's Theorem is to say that things that were once in contact are always in contact. The two sisters are somehow always connected, so that when observed jointly there is always a single pair of red, and a single pair of black, panties. Despite the fact that before the observation of the first pair of panties, there is probability one-half that either pair is red, and one-half that either pair is black."

Alternatively the girls only have one pair of panties between them, one red and one black. So the above observations are inevitable. (this is a serious point WRT entanglement)
