mf - story #5431 - Disingenuous. Quantu

Disingenuous. Quantum entanglement does not violate Relativity.

One of many many explanations why: http://curious.astro.corn...n.php?number=612

"Quantum entanglement still does not imply faster than light communication. You cannot affect which state the particle goes into, even though it doesn't 'decide' on its state until you observe it."

Good call. "Tipping one" and "forcing the other" certainly imply a transfer of something. Fucking LIARS! Physicists would make great politicians.

>Fucking LIARS! Physicists would make great politicians."

What are you talking about? You grabbed a lay description of one part of QM and you're crying that you misunderstood it? What I know of QM is that it isn't intuitive. The Math works, and is verified by collider experiments, and ultimately that is the only way to understand it - the interpretations are secondary and seem almost nonsensical (at least to me). It certainly sounds like you're trying to apply classical notions of time and matter to the quantum realm and crying that it doesn't fit.

You can't reason this out.

Although, hrm, if the act of observation effectively chooses a state, which chooses the state for the other particle 6 miles away, which (magically) didn't have a state before observation, .... maybe the description wasn't so bad. The key thing is whether the thing actually was stateless before observation. Sure it's read-only, but the *physical* act of observation (shooting photons at it or something) (not instantaneous intellectualization) physically affected a distant thing.
