What is entanglement? Itamar Pittowsky claimed that these results brought us right to the precipice of logical contradiction--but not over. Abner Shimoney described it as a piece of "experimental metaphysics." I'm a nobody, but I think entanglement is the most interesting thing ever discovered.

very jealous of people who can understand physics. i find it is like scaling a sheer wall that is also mysteriously greasy??

The previous discussions of particle localization were (imo) confused by a three-fold conflation on my part; namely, between:
1. What is the *description* of objects, particles, etc, when they appear to be localized? i.e., literally which state vector do they occupy at those times?
1. What is the *description* of objects, particles, etc, when they appear to be localized? i.e., literally which state vector do they occupy at those times?
Okay so I don't actually buy this.
Entanglement has complicated causality, but even so we must be sure to rule out superluminal signaling. That is, correlations between remote outcomes are fine, but there absolutely cannot be correlations between a selected action of mine and remote outcomes.

I finally internalized the obvious: my presence on earth (whatever this means vis-a-vis the QFT state) increasing (or being functionally related in any way to) the probability of a photon deflection in andromeda is *not* evidence of a causal relationship. It is an expression of entanglement.

you could say CDP is for securing the approximate idea of subsystems, CCR is for locality. different things.
the problem is that the above charge will only propogate its influence along null geodesics. whereas, in QFT, there is some chance i scatter a photon in andromeda *right now.*

But why does it happen?
In Feynman's approach to QED, the number of diagrams needed to calculate the α^n term in the series grows rapidly with n. Their sum eventually overwhelms even large powers of α!

he's all-good in sense that you say "we all good?" after you fuck up. yea man we all good.
If God is all-good, there are a LOT of errors in the Bible.
