Parallel Universes revisited.

[Iain17]

Time to throw some new fuel on the fire.

I was talking to my brother last night, and he brought up some interesting new points. This has to do with the uncertainty principle, and parallel universes.


Did you know they have made a monitor that can project an image without firing any electrons! I certainly did not till last night. The way they do this is bloody clever, and bloody stupid at the same time. Obviously my first reaction was, "pull the other one, its got bells on", but he insisted that he was deadly serious. So obviously my first question was, How?

They do it using parallel universes. Electrons in the parallel universe cause an interference in ours. This interference is detectable somehow. I am not sure how up on parallel universes everyone is, so a little explanation may be in order. Parallel universes are considered to be the same universe as ours that went down a different path. Every choice that can be made produces two or more parallel universe with all the possible outcomes for this choice. So in another universe, i will not be typing this post.

Back to the monitor. Even though the monitor does not fire any electrons in out universe, it must have an electron gun. If it has an electron gun, then there are two or more things that can happen. The electron gun can fire, or it could not fire, or it could blow up, or it could decide to "tunnel" its way to Australia.

The way it works is that in this universe the Gun is not fired. Yet according to the way parallel universes work, the Gun has fired in another universe. Somehow, i have no idea how, we can detect the interference caused in our universe by the electrons firing in the other universe.

Now this principle could be used to find out the exact position of an electron in our universe. You all know about the uncertainty principle, well this negates it. We set up our electron detector, and we do not fire the guns. Yet in another universe the guns were fired. This means that we can detect the interference of the electron that we hit, and know the exact position of said electron in our world, because the electron in our world did not get hit.

Just had to start it again huh? Okay, heres another 300 reply post...

Honestly, the other one's got bells on, you should try pulling it sometime.

"pull the other one, its got bells on"

is this a british expression? i don't get it.


Iain:

Are you serious about this stuff? If so, that's truly amazing. I would like to see some reference material to probe this further.

Sorry lads, I have just spoke to my brother about this again, and he said he got it wrong. They have not produced a monitor that works like that. What they have done is be able to detect what a picture looks like without bouncing any particles off it.

This is the same principle however. They detected the quantum interference from “Ghost” atoms, and were able to see what the picture looked like.

Again, this applies to the uncertainty principle. We can detect the “ghost” electron, and thus know exactly where the real electron really is.

This is all in new scientist. Look it up if you like.

pull the other one, its got bells on it

From Brewer’s Dictionary of Phrase and Fable :

To pull someone’s leg. To delude him in a humorous way, lead him astray by chaff, exaggeration, etc.

By saying that you are letting the person know that you believe they are taking you for the fool. I don’t know if you knew but fools / jesters always had bells on them. So you are saying, yeah I’m a fool, try the other leg its got bells on it.

Doesn't that do something with probabilities that the atom will be there, or something. Am I making any sense...probably not...

[dvst8]

ok tahnks Iain!

i remember reading about this ghost atom business as well. as to do with the two focii of an ellipse...you place an atom ot one focus and the ghost atom appears, at 1/3 the intensity at the other focus.

they believe that they will be able to carry out chemical reactions with these ghost atoms.

that's pretty cool.

but i don't think any of this involves parallel universes....
