Another One: Interaction at a Distance

[cosmicDASD]

OK, here's another one that has been puzzling me for some time.

When particles interact at a distance it seems obvious to me that they are conveying information through a dimension other than 3+time.

The very definition of the question begs this answer.

Why do people not talk about this, but simply say it is a conundrum?

Hi,

At a distance interactions are usually explained by either an exchange of virtual particles or by an extended field structure.

I think cosmicDASD is taking about “spooking action at a distance” or entanglement. This in fact to anyone’s knowledge does not transmit information, that is as far as I have ever heard.

I thought entanglement meant that intractions with one of the two particles was reflected in the other particle.

Isn't that, in effect, information? :confused:

Thanks!

two entangled particles A and B.

If particle A is measured then you know the state of B. Even if B is to far away to measure. However there is no way, as far as anyone knows, for someone to change the state of b and have the change be received by someone measuring A.

"I thought entanglement meant that intractions with one of the two particles was reflected in the other particle."
This is an incorrect statement. Interaction with one of the two particles is not reflected in the other particle.

Entanglement is a superposition of Quantum states. If a measurement is made on particle A or particle B the system will be found in one of the quantum states that made up the superposition.
