Quantum Entanglement

[catbirdseat]

I thought the smartest guy on cc.com would post this first, but now I guess I'll have to. I thought this was pretty cool stuff. Very weird stuff indeed.

 

I don't see any reason why this experiement shouldn't work.

 

Receiving a signal before it is sent.

Ooops, sorry. Distracted by work.

 

Carry on.

I didn't have any internet connection for the last 4 days and this news is 4 days old.

what's more, because the reporting the news involved entagled photons, you found out 5 days ago.

[G-spotter]

Actually I found out 15 years ago. Some guy with a DeLorean told me.

What about The EPR Paradox?

 

How does this proposed experiment not violate Einstein's postulate that c is the "universal speed limit"? Information would have to travel as light extra-dimensionally.

 

Wouldn't both of the detectors involved have to be "tuned" to either detect particle or wave behavior? It's not like a photon comes out and you say "that one's a particle" or "that ones a wave"

[catbirdseat]

You need to read up on the subject. The photon has a dual nature. It is both a wave and a particle, but depending on how it is measured it can appear as one or the other. If you find that one of the two is behaving as a particle then, you will find that the other is also.

 

How are you violating Einstein's postuate? The speed of light in a vacuum is c, but the velocity is slower through matter, like the glass or plastic of a fiber optic cable.

[G-spotter]

Inflation happened faster than c cause the vacuum itself was expanding

The universe isn't really a vacuum. It is filled with a Higgs Ocean.

No shit, Sherlock. The article suggested that they would change the wave/particle nature of one photon, and the other would learn of the change before it happened. For one, you can only measure either partcle or wave behavior, not both simultaneously. You'd need either a photometer (to measure particle characteristics) or a diffraction grating and an interferometer (to measure wave characteristics), for example. You can't have both.

 

The information regarding the wave/particle state in these entanglement scenarios seems to travel instantaneously. This violates Einstein's postulate. In the proposed experiment, the information travels backwards in time. As the arrow of time only "points" forward, this information would have to travel extradimensionally, IMHYAWRO, TYCDH.

 

Additionally:

 

The "Higgs Ocean" is purely theoretical. The Higgs boson has yet to be discovered, perhaps after 2007 when the Large Hadron Collider comes online at CERN. And don't even start with Super-Strings, they are about as valid as the GSM model.

 

Dru: c has not been constant throughout the history of the universe.

 

Food for thought: What about entangled particles where one falls into a Black Hole? How does the other "know" the state of it's companion if information (light) cannot escape the event horizon?

[catbirdseat]

I have read about experiments in which entangled photons have been made to travel great distances before being "queried" as to their properties. They found that no matter what the distance, forcing one photon to give up information caused the partner photon to do likewise. But we know that this phenomenon cannot be used to transmit information faster than the speed of light.

Hawking Radiation

 

Hawking Radiation consists of particles/antiparticles from particle/antiparticle pairs where one of the members of the pair has gone beyond the event horizon into the black hole and the other has escaped (excluding for this discussion black hole evaporation). What if particle one of an entangled pair has already passed the event horizon, and it is "modified" within the black hole? The second particle, because of the entanglement, is "informed" of this modification instantly, violating Einstein's postulate.

[G-spotter]

particle/antiparticle pairs are themselves not entangled.

[Choada_Boy]

particle/antiparticle pairs are themselves not entangled.

 

No statement was made to that effect.

i also like people who think they are smart enough to know who is the smartest. there is a sure sign of geniousity.

I am the psychotherapist. Please, describe your problems. Each time

you are finished talking, type RET twice.

 

The fact that 47 PEOPLE are yelling and sweat is cascading

down my SPINAL COLUMN is fairly enjoyable!!

 

Is it because 47 people are yelling and sweat is cascading down your

spinal column is fairly enjoyable that you came to me?

 

If I felt any more SOPHISTICATED I would DIE of EMBARRASSMENT!

 

This is not a healthy way of thinking.

 

I'm having a RELIGIOUS EXPERIENCE.. and I don't take any DRUGS

 

Why do you say and you do not take any drugs?

 

Am I in GRADUATE SCHOOL yet?

 

Tell me about your school.

 

..Are we having FUN yet...?

 

Earlier you said 47 people are yelling and sweat is cascading down

your spinal column is fairly enjoyable?

 

It's OKAY --- I'm an INTELLECTUAL, too.

 

Maybe your plans have something to do with this.

 

Jesus is my POSTMASTER GENERAL..

 

Is it because of your life that you say jesus is your postmaster

general?

 

A GRAM?? A BRAM... A GROOM... A BROOM... Oh, Yeh!! Wash the

ROOM!!

Wouldn't it be super cool if the last post of a thread went up before the first post on the topic were made?

[ketch]

Arch you are assuming that there is a coherant signal somehow connected to a post on this board.
